fp42) Petcock vacuum diaphram RETURN SPRING. The return spring should always be replaced (or, the original spring shimmed with the HCP663 shimming washer) as a normal part of a petcock rebuild procedure.

HCP13145 Aftermarket petcock vacuum diaphram RETURN SPRING. One of the many causes of a leaking petcock is a diaphram return spring that has weakened over time. These replacements are produced to a slightly longer specification than stock, resulting in approximately 10% greater spring pressure operating upon the vacuum diaphram disc (and thus upon the plunger sealing o-ring), thus helping to compensate for other worn original parts and helping to insure a leak-proof rebuild. Highly recommended when rebuilding any stock petcock. For use with all XJ550, 1984-85 FJ600, XJ650 (except Turbo), all 1981-83 XJ750 models, and all XS1100 Standard model petcocks.

HCP23615 Aftermarket petcock vacuum diaphram RETURN SPRING. One of the many causes of a leaking petcock is a diaphram return spring that has weakened over time. These replacements are produced to a slightly longer specification than stock, resulting in approximately 10% greater spring pressure operating upon the vacuum diaphram disc (and thus upon the plunger sealing o-ring), thus helping to compensate for other worn original parts and helping to insure a leak-proof rebuild. Highly recommended when rebuilding any stock petcock. For use with the 1986-88 FZ600, 1992-98 XJ600 Seca II, and the HCP626 or HCP28771 petcocks only.
$ 11.95

HCP663 Aftermarket vacuum control module vacuum diaphram SPRING SHIM WASHER. This washer goes behind the vacuum diaphram plunger spring and acts as a tension shim to allow the spring to put more pressure on the replacement-style o-ringed plunger tip, and thus allowing it to seat and seal properly. Used on all XJ550, 1984-85 FJ600, 1986-88 FZ600, all XJ650 (except Turbo), all XJ700, XJ750RL, XJ750-X, XJ900RK, RL, N/FN, and F models, and all XS1100 Standard model petcocks,and the vacuum control unit on XJ1100, XS1100 Special, and XS1100 Midnight Special models. This washer goes under the spring and fits into the recessed well in the cover plate.
$ 1.95




fp3) Aftermarket petcock fuel control VACUUM DIAPHRAM REPAIR PARTS. The vacuum diaphram, located underneath the vacuum plate on the "rear" of the petcock body, consists of the fuel shut-off plunger needle (with an o-ringed plunger tip) attached to a dual-diaphram metal disc. A spring provides pressure against this disc, which in turn forces the o-ringed plunger tip to seal closed against a beveled seat in the petcock body, thus shutting off fuel flow when the engine vacuum is absent (i.e. when the engine is off).

A number of problems can and do occur with this system which result in either petcock failure (no fuel flow, at all) or with a petcock that constantly leaks fuel flow (a petcock that never truly shuts "off", which can result in flooded carbs, fuel in the crankcase, fuel leakage and fire hazards, etc.). Typically, the o-ring on the plunger tip fails or gets deformed over time, the vacuum diaphragms get brittle, torn, or otherwise rupture, or the pressure spring weakens and loses its tension. In most original 25+ year old petcocks, all three of these problems are common.

Offered below are both standard and deluxe versions of the VACUUM DIAPHRAM REPAIR KITS and PETCOCK REBUILD KITS which contain the parts needed to fully rebuild your factory petcock.


HCP110 Aftermarket petcock fuel control VACUUM DIAPHRAM, without the plastic spacer plate.

We strongly recommend the use of either the HCP663 spring shim washer or the HCP13145 replacement spring (not included) when rebuilding original petcocks. NOTE: you must save and re-use your original plastic spacer plate!
$ 39.95

HCP2282 Aftermarket petcock fuel control VACUUM DIAPHRAM, complete with the plastic spacer plate.

$ 34.95




fp42) Petcock vacuum diaphram CHECK VALVE. This small, round plastic disc (original is bakelite) anti-backfire valve fits into the vac diaphram cover plate behind the vacuum hose brass nipple, and prevents a engine backfire from migrating up thru the intake manifold, thru the vac hose to the petcock, and into the petcock body.....a very bad thing to happen! You can see it here:

http://www.xjbikes.com/forums/threads/rebuilding-the-yamaha-vacuum-fuel-valve-w-pics.25058/page-3


Generally, this disc never needs replacing unless it is lost or goes missing during a rebuild ---- but, it needs to be there!. Using a petcock without this "valve" is like wishing for a death sentence!

HCP19586 Aftermarket petcock vacuum diaphram CHECK VALVE. Used on all XJ550, FJ600, XJ650 (except Turbo), XJ700, XJ750, XJ900, and XJ1100 models (use on the vacuum module on XJ1100 and XS1100 Special/Midnight Special models).

fl4) OEM Yamaha and aftermarket petcock IN-TANK FUEL FILTERS are your first defense against crud and grit getting into your carbs and causing problems with worn float needle valves and/or carb flooding.

HCP116 OEM petcock in-tank FUEL FILTER. This is the tall, white filter unit (yours may have turned brown after all these years) that fits onto the petcock and goes up into the tank. 94mm (about 3-3/4") tall, which may differ slightly from the stock filter height, but it doesn't interfere with anything and doesn't change the performance. It's a swell idea to clean or replace this filter whenever you have the petcock out for servicing. Fits all XJ550, XJ650 (except Turbo models), all XJ700, XJ750 (except XJ750-D), XJ900RK, XJ1100, and all XS1100 Special/Midnight Special models.
$ 43.95

NOTES ON USE OF THE HCP116 FILTER:
- some original petcocks used a shorter 2" tall filter, which is no longer available, and this taller filter will work just fine in place of it, but may change the determination point of when the "reserve" supply level is reached.

- some minor trimming and/or "shaping" of the oval base of the filter may be necessary to insure a proper fit, as the filter base is very slightly oversized for some original petcocks, as can be seen in this thread: http://xjbikes.com/forums/index.php?threads/25058

- original filters on XJ1100 and XS1100 Special models had a smaller diameter locating “peg” on the bottom of the filter, so some trimming and fitting will be needed on those models.

- on some petcocks, this filter can fit "either way" into the petcock body, so that the ON and RES locations could become reversed! Make sure you install it in the proper orientation!!




HCP23713 Aftermarket replacement mesh FUEL FILTERS, will fit (with a bit of work) our HCP625, HCP626, original XJ650 Turbo petcocks, 1986-88 FZ600 petcocks, and the 1992-98 XJ600 Seca II petcocks in both inlet positions, but: on the "reserve" (shorter) position, you must save and re-use the short base "bushing" of the original filter, as it is the proper size to fit into the machined opening in the petcock body. The replacement straw filter will then fit snugly into this bushing. On the main fuel plastic standpipe, you will also need to save and re-use the short base "bushing" of the original filter, or you use the included 1/4" ID hose "coupler" to secure the filter to the metal pipe. Set of 2 filters:
$ 22.95




XJ650 Turbo, XJ700, XJ750-X, XJ750RL, and XJ900RK, RL, N/FN, and F models:

NOTE: XJ650 Turbo petcocks do not use any of the vacuum-diaphram bits and pieces listed below, since they are not vacuum-actuated.

NOTE: the following parts will fit the original XJ series petcock only!

NOTE: there is an issue with some XJ700, XJ750-X, and XJ900 petcocks, and the XS/XJ1100 fuel distribution valve bodies where the o-ring seat for the diaphragm plunger was not drilled "straight" (perpendicular) to the mounting face for the diaphragm.......this is possibly why the original petcocks used a hollow o-ring, that would deform more easily to compensate for this (slight) mis-alignment situation......although this issue normally manifests itself as a drip-drip-drip type of leak, rather than a "pouring out" type of leak.

On the affected petcocks, we’ve found that it is necessary to slightly “lengthen” the plunger shaft distance, and the best way to do this is to use an appropriate sized deep-well socket, and place the plunger shaft/tip down into the well of the socket……so that the round metal disc will be sitting on the top of the socket opening, with the plunger shaft down inside the socket well.

Now, take a small hammer (or hammer-like object) and GENTLY tap on the tip of the shaft sitting above the disc, thus “dimpling” the disc in the center JUST SLIGHTLY and thus moving the plunger tip (with the o-ring) “closer” to the seat in the petcock body. This dimpling should BARELY make a concave surface out of the round. previously-flat disc.

As mentioned, some of these petcocks actually had their o-ring seat drilled slightly off-center (or cockeyed) in relation to the plunger shaft…….original plungers used a HOLLOW o-ring that could easily deform to make up for this slightly off-kilter orientation of the shaft vs. the seat. The replacement plungers use a standard, solid o-ring and this cannot deform as much as the original hollow o-rings do. By dimpling the support disc, and in effect “extending” the length of the plunger shaft, the solid o-ring can take up any tiny amount of slack caused by this non-alignment issue.

fp42) Petcock vacuum diaphram RETURN SPRINGS. The return spring should always be replaced (or, the original spring shimmed with the HCP663 shimming washer) as a normal part of a petcock rebuild procedure.

HCP13146 Aftermarket vacuum control module diaphram RETURN SPRING. One of the many causes of a leaking petcock is a diaphram return spring that has weakened over time. These replacements are produced to a slightly longer specification than stock, resulting in approximately 10% greater spring pressure operating upon the vacuum diaphram disc (and thus upon the plunger sealing o-ring), thus helping to compensate for other worn original parts and helping to insure a leak-proof rebuild. Highly recommended when rebuilding any stock petcock. For use with all XJ700, XJ750RL, XJ750-X, XJ900RK, RL, N/FN, and F models, and the vacuum control unit on XJ1100, XS1100 Special, and XS1100 Midnight Special models. Each.
$ 11.95

HCP663 Aftermarket vacuum control module vacuum diaphram SPRING SHIM WASHER. This washer goes behind the vacuum diaphram plunger spring and acts as a tension shim to allow the spring to put more pressure on the replacement-style o-ringed plunger tip, and thus allowing it to seat and seal properly. Used on all XJ700, XJ750RL, XJ750-X, XJ900RK, RL, N/FN, and F models, and all XS1100 Standard model petcocks,and the vacuum control unit on XJ1100, XS1100 Special, and XS1100 Midnight Special models. This washer goes under the spring and fits into the recessed well in the cover plate.
$ 1.95

HCP1658 Aftermarket petcock plunger O-RING, fits at the end of the plunger tip and seals the plunger to the beveled seat in the petcock body. Solid rather than hollow like an original o-ring. Fits all original and aftermarket vacuum diaphram plungers on all XJ-series original petcocks. NOTE: all of our replacement vacuum diaphram units come with this o-ring already included and installed on the plunger!
$ 3.95




fp3) Aftermarket petcock fuel control VACUUM DIAPHRAM. The vacuum diaphram unit, located underneath the vacuum plate on the "rear" of the petcock body, consists of the fuel shut-off plunger needle (with an o-ringed plunger tip) attached to a dual-diaphram metal disc. A spring provides pressure against this disc, which in turn forces the o-ringed plunger tip to seal closed against a beveled seat in the petcock body, thus shutting off fuel flow when the engine vacuum is absent (i.e. when the engine is off).

A number of problems can and do occur with this system which result in either petcock failure (no fuel flow, at all) or with a petcock that constantly leaks fuel flow (a petcock that never truly shuts "off", which can result in flooded carbs, fuel in the crankcase, fuel leakage and fire hazards, etc.). Typically, the o-ring on the plunger tip fails or gets deformed over time, the vacuum diaphragms get brittle, torn, or otherwise rupture, or the pressure spring weakens and loses its tension. In most original 25+ year old petcocks, all three of these problems are common.

NOTE: there is an issue with some XJ700, XJ750-X, and XJ900 petcocks, and the XS/XJ1100 fuel distribution valve bodies where the o-ring seat for the diaphragm plunger was not drilled "straight" (perpendicular) to the mounting face for the diaphragm.......this is possibly why the original petcocks used a hollow o-ring, that would deform more easily to compensate for this (slight) mis-alignment situation......although this issue normally manifests itself as a drip-drip-drip type of leak, rather than a "pouring out" type of leak.

On the affected petcocks, we’ve found that it is necessary to slightly “lengthen” the plunger shaft distance, and the best way to do this is to use an appropriate sized deep-well socket, and place the plunger shaft/tip down into the well of the socket……so that the round metal disc will be sitting on the top of the socket opening, with the plunger shaft down inside the socket well.

Now, take a small hammer (or hammer-like object) and GENTLY tap on the tip of the shaft sitting above the disc, thus “dimpling” the disc in the center JUST SLIGHTLY and thus moving the plunger tip (with the o-ring) “closer” to the seat in the petcock body. This dimpling should BARELY make a concave surface out of the round. previously-flat disc.

The replacement plungers use a standard, solid o-ring and this cannot deform as much as the original hollow o-rings do. By dimpling the support disc, and in effect “extending” the length of the plunger shaft, the solid o-ring can take up any tiny amount of slack caused by this non-alignment issue.

fp42) Petcock vacuum diaphram CHECK VALVE. This small, round plastic disc (original is bakelite) anti-backfire valve fits into the vac diaphram cover plate behind the vacuum hose brass nipple, and prevents a engine backfire from migrating up thru the intake manifold, thru the vac hose to the petcock, and into the petcock body.....a very bad thing to happen! You can see it here:

http://www.xjbikes.com/forums/threads/rebuilding-the-yamaha-vacuum-fuel-valve-w-pics.25058/page-3

fl4) OEM Yamaha and aftermarket petcock IN-TANK FUEL FILTERS are your first defense against crud and grit getting into your carbs and causing problems with worn float needle valves and/or carb flooding.

HCP116 OEM petcock in-tank FUEL FILTER. This is the tall, white filter unit (yours may have turned brown after all these years) that fits onto the petcock and goes up into the tank. 94mm (about 3-3/4") tall, which may differ slightly from the stock filter height, but it doesn't interfere with anything and doesn't change the performance. It's a swell idea to clean or replace this filter whenever you have the petcock out for servicing. Fits all XJ550, XJ650 (except Turbo models), all XJ700, XJ750 (except XJ750-D), XJ900RK, XJ1100, and all XS1100 Special/Midnight Special models.
$ 43.95

NOTES ON USE OF THE HCP116 FILTER:
- some original petcocks used a shorter 2" tall filter, which is no longer available, and this taller filter will work just fine in place of it, but may change the determination point of when the "reserve" supply level is reached.

- some minor trimming and/or "shaping" of the oval base of the filter may be necessary to insure a proper fit, as the filter base is very slightly oversized for some original petcocks, as can be seen in this thread: http://xjbikes.com/forums/index.php?threads/25058

- original filters on XJ1100 and XS1100 Special models had a smaller diameter locating “peg” on the bottom of the filter, so some trimming and fitting will be needed on those models.

- on some petcocks, this filter can fit "either way" into the petcock body, so that the ON and RES locations could become reversed! Make sure you install it in the proper orientation!!



HCP23713 Aftermarket replacement mesh FUEL FILTERS, will fit (with a bit of work) our HCP625, HCP626, original XJ650 Turbo petcocks, 1986-88 FZ600 petcocks, and the 1992-98 XJ600 Seca II petcocks in both inlet positions, but: on the "reserve" (shorter) position, you must save and re-use the short base "bushing" of the original filter, as it is the proper size to fit into the machined opening in the petcock body. The replacement straw filter will then fit snugly into this bushing. On the main fuel plastic standpipe, you will also need to save and re-use the short base "bushing" of the original filter, or you use the included 1/4" ID hose "coupler" to secure the filter to the metal pipe. Set of 2 filters:
$ 22.95




XJ1100 and XS1100 models:

Please note that XJ1100 and XS1100 Special/Midnight Special models use a separate vacuum control module to control the on-off feature to both of the original petcocks, and thus to rebuild the "petcocks" you typically will need to rebuild both of the fuel valves (the "petcocks") as well as the vacuum control module.

NOTE: the following parts will fit the original XJ1100 and XS1100 series petcocks and vacuum control unit only!

A great visual journal of petcock rebuilding procedures can be found at:

http://xjbikes.com/forums/index.php?threads/25058

Although the above guide pertains to the “integrated” petcocks found on many models, the same tasks and procedures also apply to the passive fuel valves and the separate vacuum “octopus” as found on some 1100 models.

p311) OEM petcock VACUUM CONTROL MODULE PARTS, for use on XJ1100 and all XS1100 Special/Midnight Special models. These models petcocks had their "automatic on-off" functionality enabled by a remotely mounted vacuum control module unit which control the fuel flow through the petcocks (that's why there is the "rat nest" of fuel and vacuum lines going everywhere on these carbs!). A leaking or ruptured diaphram, or a weak diaphram return spring within this control module, will allow the petcocks to remain "on" all the time..........not a good situation!

HCP5375 OEM complete VACUUM CONTROL MODULE, with the small mounting bracket, for all XJ1100 and all XS1100 Special/Midnight Special models, Does NOT include the c-shaped carb hat bracket. Each:
$ 249.95



fp3) Aftermarket vacuum control module fuel control VACUUM DIAPHRAM. The vacuum control module diaphram unit, consists of the fuel shut-off plunger needle (with an o-ringed plunger tip) attached to a dual-diaphram metal disc. A spring provides pressure against this disc, which in turn forces the o-ringed plunger tip to seal closed against a beveled seat in the module body, thus shutting off fuel flow when the engine vacuum is absent (i.e. when the engine is off).

A number of problems can and do occur with this system which result in either petcock failure (no fuel flow, at all) or with a petcock that constantly leaks fuel flow (a petcock that never truly shuts "off", which can result in flooded carbs, fuel in the crankcase, fuel leakage and fire hazards, etc.). Typically, the o-ring on the plunger tip fails or gets deformed over time, the vacuum diaphragms get brittle, torn, or otherwise rupture, or the pressure spring weakens and loses its tension. In most original 25+ year old units, all three of these problems are common.


fp3) Aftermarket vacuum control unit fuel control VACUUM DIAPHRAM. You must save and re-use your original plastic spacer plate!

HCP1657 Aftermarket fuel control VACUUM DIAPHRAM. Fits all XJ1100 and all XS1100 Special/Midnight Special models. We strongly recommend the use of either the HCP663 spring shim washer or the HCP13146 replacement spring (not included) when rebuilding original vacuum control units on the these models. NOTE: you must save and re-use your original plastic spacer plate!

$ 29.95




fp42) Petcock vacuum diaphram CHECK VALVE. This small, round plastic disc (original is bakelite) anti-backfire valve fits into the vac diaphram cover plate behind the vacuum hose brass nipple, and prevents a engine backfire from migrating up thru the intake manifold, thru the vac hose to the petcock, and into the petcock body.....a very bad thing to happen! You can see it here:

http://www.xjbikes.com/forums/threads/rebuilding-the-yamaha-vacuum-fuel-valve-w-pics.25058/page-3


Generally, this disc never needs replacing unless it is lost or goes missing during a rebuild ---- but, it needs to be there!. Using a petcock without this "valve" is like wishing for a death sentence!

HCP19586 Aftermarket petcock vacuum diaphram CHECK VALVE. Used on all XJ550, FJ600, XJ650 (except Turbo), XJ700, XJ750, XJ900, and XJ1100 models (use on the vacuum module for XJ1100's).

fp42) Petcock vacuum control module diaphram RETURN SPRINGS. The return spring should always be replaced (or, the original spring shimmed with the HCP663 shimming washer) as a normal part of a vacuum control module rebuild procedure.

HCP13145 Aftermarket petcock vacuum diaphram RETURN SPRING. One of the many causes of a leaking petcock is a diaphram return spring that has weakened over time. These replacements are produced to a slightly longer specification than stock, resulting in approximately 10% greater spring pressure operating upon the vacuum diaphram disc (and thus upon the plunger sealing o-ring), thus helping to compensate for other worn original parts and helping to insure a leak-proof rebuild. Highly recommended when rebuilding any stock petcock. For use with all XJ550, 1984-85 FJ600, XJ650 (except Turbo), all 1981-83 XJ750 models, and all XS1100 Standard model petcocks.

fp42) Petcock vacuum diaphram RETURN SPRING. The return spring should always be replaced (or, the original spring shimmed with the HCP663 shimming washer) as a normal part of a petcock rebuild procedure.

HCP23615 Aftermarket petcock vacuum diaphram RETURN SPRING. One of the many causes of a leaking petcock is a diaphram return spring that has weakened over time. These replacements are produced to a slightly longer specification than stock, resulting in approximately 10% greater spring pressure operating upon the vacuum diaphram disc (and thus upon the plunger sealing o-ring), thus helping to compensate for other worn original parts and helping to insure a leak-proof rebuild. Highly recommended when rebuilding any stock petcock. For use with the 1986-88 FZ600, 1992-98 XJ600 Seca II, and the HCP626 or HCP28771 petcocks only.

HCP663 Aftermarket petcock vacuum diaphram SPRING SHIM WASHER. This washer goes behind the vacuum diaphram plunger spring and acts as a tension shim to allow the spring to put more pressure on the replacement-style o-ringed plunger tip, and thus allowing it to seat and seal properly. Used on all XJ550, 1984-85 FJ600, 1992-98 XJ600 Seca II, XJ650 (except Turbo), XJ700, XJ750, XJ900, and XJ1100 models (use on the vacuum module for 1100's), as well as with our HCP625 and HCP626 petcocks. This washer goes under the spring and fits into the recessed well in the cover plate.

fp3) Aftermarket petcock fuel control VACUUM DIAPHRAM. The vacuum diaphram unit, located underneath the vacuum plate on the "rear" of the petcock body, consists of the fuel shut-off plunger needle (with an o-ringed plunger tip) attached to a dual-diaphram metal disc. A spring provides pressure against this disc, which in turn forces the o-ringed plunger tip to seal closed against a beveled seat in the petcock body, thus shutting off fuel flow when the engine vacuum is absent (i.e. when the engine is off).

A number of problems can and do occur with this system which result in either petcock failure (no fuel flow, at all) or with a petcock that constantly leaks fuel flow (a petcock that never truly shuts "off", which can result in flooded carbs, fuel in the crankcase, fuel leakage and fire hazards, etc.). Typically, the o-ring on the plunger tip fails or gets deformed over time, the vacuum diaphragms get brittle, torn, or otherwise rupture, or the pressure spring weakens and loses its tension.


HCP18235 Aftermarket petcock fuel control VACUUM DIAPHRAM. Fits all 1986-88 FZ600, 1992-98 XJ600 Seca II models, and the HCP626 or HCP28771 petcocks. We strongly recommend the use of the HCP663 diaphram spring shim not included when rebuilding original petcocks. NOTE: you must save and re-use your original plastic spacer plate!

fl4) OEM Yamaha and aftermarket petcock IN-TANK FUEL FILTERS are your first defense against crud and grit getting into your carbs and causing problems with worn float needle valves and/or carb flooding.

HCP23713 Aftermarket replacement mesh FUEL FILTERS, will fit (with a bit of work) our HCP625, HCP626, original XJ650 Turbo petcocks, 1986-88 FZ600 petcocks, and the 1992-98 XJ600 Seca II petcocks in both inlet positions, but: on the "reserve" (shorter) position, you must save and re-use the short base "bushing" of the original filter, as it is the proper size to fit into the machined opening in the petcock body. The replacement straw filter will then fit snugly into this bushing. On the main fuel plastic standpipe, you will also need to save and re-use the short base "bushing" of the original filter, or you use the included 1/4" ID hose "coupler" to secure the filter to the metal pipe. Set of 2 filters:

fl4) OEM Yamaha and aftermarket petcock IN-TANK FUEL FILTERS are your first defense against crud and grit getting into your carbs and causing problems with worn float needle valves and/or carb flooding.

HCP116 OEM petcock in-tank FUEL FILTER. This is the tall, white filter unit (yours may have turned brown after all these years) that fits onto the petcock and goes up into the tank. 94mm (about 3-3/4") tall, which may differ slightly from the stock filter height, but it doesn't interfere with anything and doesn't change the performance. It's a swell idea to clean or replace this filter whenever you have the petcock out for servicing. Fits all XJ550, XJ650 (except Turbo models), all XJ700, XJ750 (except XJ750-D), XJ900RK, XJ1100, and all XS1100 Special/Midnight Special models.
$ 43.95

NOTES ON USE OF THE HCP116 FILTER:
- some original petcocks used a shorter 2" tall filter, which is no longer available, and this taller filter will work just fine in place of it, but may change the determination point of when the "reserve" supply level is reached.

- some minor trimming and/or "shaping" of the oval base of the filter may be necessary to insure a proper fit, as the filter base is very slightly oversized for some original petcocks, as can be seen in this thread: http://xjbikes.com/forums/index.php?threads/25058

- original filters on XJ1100 and XS1100 Special models had a smaller diameter locating “peg” on the bottom of the filter, so some trimming and fitting will be needed on those models.

- on some petcocks, this filter can fit "either way" into the petcock body, so that the ON and RES locations could become reversed! Make sure you install it in the proper orientation!!

cps2) Aftermarket high-quality WET-OR-DRY FINISHING SHEETS. Since these don't contain "sand", we really can't call them "sandpaper", but you get the idea. A large assortment of ultra-fine finishing paper is just the trick to polish all of the mating surfaces and the selector lever rear “face” in your petcock, ridding them of any surface oxidation and minor imperfections that will prevent the from seating properly. Our recommendation is to start with the 400-grit paper and then use the 600- and 800-grits until you get the surfcaes micro-polished to an incredible smooth finish. One 9.5" x 11" sheet of each size will be enough to do many petcocks. We recommend that you place the paper face up on a flat piece of glass (glass is a really smooth, flat surface), wet the paper with ED40 or the like, and then move the surface to be polished in a back-and-forth and a figure-8 pattern to remove all imperfections and high spots.
