I found a Jaguar pick up sock to replace my original. It is so close to being the right size. It fits on the pipe, but not quite tight enough. I think if i can put a thin layer of epoxy or some other thing on the tube, it will be perfect. Any ideas about what i can use that will survive in there?

 

Permatex has a gas tank repair epoxy, Jb weld has two wet rated products : https://www.jbweld.com/pages/faqs

 

JB weld looks like a winner. Thanks.

 

You could deform the tube a bit where it meets the filter for a friction fit.

 

i'm going to see if a friend of mine can machine a sleeve to go over the tube. I thought about trying to stretch/deform the tube a bit, but if it splits, i'll be sad.
I could also put a ring of solder on the tube, right? that seems pretty easy too.

 

Or a rubber tube (like shrink fit tubing) to get a friction fit with no glue or anything. Just have to make sure its fuel safe.

 

Yep. that's on my list too. or if they sold tiny amounts of the stuff you line a tank with. That is like a paint coating, right?

 

What about a plumbing ferrule used for compression fittings?

 

those are close. but too thick. i would have to sand? them down. I guess if i can think of a way to do that and keep it round it could work. I have brass tubes i use for making pens that would work great. but i didn't have any that were 12mm ID. That doesn't mean they don't exist. I can look into that too.

 

nice find...I would think a ring of solder would be too much, I would just put a dab on one side, push the sock in place and maybe half a turn of the sock so deformed part of the plastic is now on the opposite side.

 

Ok, this is what i went with. It's a marine grade shrink tubing. The metal sleeve would have been so thin, it would have been hard to put on. Even this shrink tube is too thick. I had to shave it down a bit with a razor. I really think something that could have been painted on would have worked best. But I didn't want to buy something like that and only use a tiny bit.

BTW, this is the fuel filter I used.

 

Stick a sample of that heat shrink into a cup of gas and see if it gets attacked, heck maybe leave it in a jar sealed and you can watch how it degrades without peeking into your tank.
