in tank clunk type fuel filter

has anyone done an in tank clunk style filter mod on their xj? I am looking at putting 2 of these inside the tank to pick up fuel from the true bottom of the tank.

I am also planning to put an inline filter between the tank and carbs as well.

Does the mounting allow this to be removed? Like, if it gets all gummed up can you swap it easily?

 

they will go on the end of some fuel tubing and attach to the fuel petcock somehow. I was asking if anyone has done this in hopes they would have a solution to attaching the tubing to the petcock. my reason for doing this is so it will use all the fuel possible, thereby getting more miles out of each tank of fuel.

no nobody does it because that's where all the rust, crud, water and other crap lives.
but once you suck all that through your carbs, you'll be in fine shape for that last two miles

 

well after I am finished restoring my tank, it will be sparkiling clean and will never be able to rust again. I am considering installing a drain bung as well to make sure I can keep it clean.

I don't think rust will be entirely possible to rule out plus the fact that fuel from the gas station could have contaminants in it that over time could plug the filter. As long as you make some allowance for accumulation in the tank a couple of ounces of fuel will not give you too much more mileage. Also, the hose you use to connect that to the petcock could deteriorate over time by being submerged in fuel 24/7 so there is that to take under consideration too.
With splitting the tank like you did, how are you going to stick it back together? Mig, Tig, bronze?
Interesting thread and +1 on your perseverance.

 

thanks for the +1. having a drain bung at the lowest point will help to control the buildup of sediment and whatever comes from the gas pump. it will also allow me to drain it for winterization. the clunk and tubing can be removed easily by taking out the petcock, so servicing the filter is not a problem. there is special fuel tubing for inside fuel tanks. Polaris uses it in most if not all of their rigs and most of your smaller power tools (read weed eaters and the like) and dirtbikes use a similar setup. once I coat the inside of the tank with the por15 fuel tank restorer, there will never be any more rust, ever. I have a mig welder and am quite proficient with it, but I would like to learn to tig weld and I think it is a better way to rejoin the two halves. I will cross that bridge when I get there. I have a friend that teaches welding and metal arts. I may just have to look him up.

How about 2 outlets at the lowest points on the tank that lead to an antique glass sediment bowl, then to an inline filter, then to the vac-operated petcock??

Advantages-
You don't have brass things bouncing around inside the tank, chipping your coating,
You don't have to service things inside your tank,
You can visually inspect for water, sediment,
Your in-tank filters were simply screens, and now you have a paper filter (better) to annually throw away.

With all the work you're doing, you should rig up a low fuel light sender that would fit into the old petcock hole.

 

Or... a variation on the above but the 2 outlets are for RES and you make a fitting to replace the tank mounted petcock and use that for ON and get one of these



Which has separate inlets for ON and RES, frame mounted and no diaphragm, inline filters before the fuel tap. Part # 2GH-24500-00 is very similar
