Show me your external filter rigs

I'm running an external in-line filter. It's a generic, clear plastic filter (also used on old air-cooled VW's). with some fuel line. It's not really secured to anything.

I hate my arrangement and I'm looking for ideas to clean it up, better filters, avoiding kinks in the line, etc. Post pictures, show me what you got!

 

I had a lawnmower filter in use. I just picked up this one.

i got one of those at NAPA, works great.

NAPA FUEL FILTER

 

Yeah, but how do you mount them? How do you route the line? Or do you? Do you clip it to anything?

 

I've got one like the one in the NAPA link - I mounted it on top between carb #1 & #2 - just cut out enough fuel line to make it fit.

When I replace it I'm going to see about getting a new piece of fuel hose, and use a right-angle filter like these at BikeBandit:
Visu-Filters

Should fit between the carbs better

 

elementjoe uses the same one as I. I used clear fuel line so I can look to see whats going on

 

I have one (actually two) that I got from chacal, looks just like the NAPA link posted above. Cut just enough line out for it to fit right in; "suspended from the line," it's fine.

 

Maybe a dumb question, but what is the reason for the inline fuel filter? How often would you change it?

 

Mine just sits on top of the carbs running the same route as if it was the fuel line. No special mounting or brackets required.

I don't have a pic, but this should give you and idea what it looks like.

here ya go

 

Props to Joe there -- that's pretty much exactly what mine looks like too, and suspecting most of us with filters!

 

fwright... With the carbs on these bikes, you really need an inline filter to make sure junk does not make it to the carbs.

The petcock has a screen on it and there are screens at the float valves, so the inline filter makes it the 'third times a charm' approach.

As far as the changing frequency, it depends on if you get a high volume of junk. Use a clear filter, and you can watch it.

 

XJ Yamahas, like a lot of Japanese bikes at the time, were subject to rust in the gas tanks even before they were delivered to customers brand new. (There were Yamaha tech bulletins at the time telling the dealers what to look for and how to fix it.)

Rust can easily dissolve into particles small enough to pass through the petcock screen, and the float valve screens are only good to stop boulders.

The inline filter isn't just "insurance" it provides FINER filtration than the stock solutions. Some of the passages in these CV carbs are really small.

 

Yup, same filter I have on mine. It's nice to be able to see if/when it gets dirty and cheap enough to carry a spare in the tool pouch.
There are L-shaped filters on the market I've seen doing a search that would work better making a 90 degree turn down to the carbs which I may look into.

 

Alright, I'm sold.
so which fuel line do you attach it to? (From the petcock to...?)

 

I run mine from the line that comes off the petcock. I have one like the one one from napa, but got it at the yamaha shop. It's actually about time I change it out this year. Thanks for the reminder. It's been 3 years.

 

There is only one fuel line, just cut out enough of the pipe to fit the filter in, I cut a bit at a time until it fitted just snug as you drop the tank down.

 

I got all gung ho about this simple mod and went to home depot (hoping it would be in the lawn mower department)... no go. After that went to Murrays Auto Parts... Again, NO GO!!! So, I guess I'll he Napa after work tomorrow or Monday.

 

Lowes has a red disk in-line filter in their mower section if you are in a pinch. Go with the clear though so that you can see what is going on.

 

You'll need to cut the gas line, so there is only about 1" coming off the petcock. Then install the filter onto the 1" piece, then clamp the existing gas line onto the other end of the filter, just before it turns down to the carbs.
My idea is to get an L-shaped filter to go where the gas line makes the bend, so it'll look a little better.
