gas tank leak

scottiegwood · Sat Apr 28th, 2007, 04:40 PM

i'm having a lot of trouble getting my gas tank to stop leaking.

the leak is coming from where the gas gauge mounts to the tank. i replaced the bolts and the gasket.... any more suggestions

no suggestions...

Did you tourque the bolts are just bear down and hope that would work? If you replaced your gasket really the only thing it could be is bolts to lose or too tight. You might also check to see if the lip or metal is bent or something that prevents a good seal.

there is a type of RTV that is gasoline rated, gold labeled i think. a thin coat on both sides of the gasket should help seal it.

Any parts store should have it.

Just thought of this as well did you check where the hose connect into the tank maybe you have a bad clamp an the gas is coming up the hose, leaking out of it at the base of the tank, and giving the impression that it is the seal that is leaking. These are just thoughts without being there it is kind of hard to really know and I do not want to insult your mechanical experience; I know I have made my mistakes (just ask Mtnairlover). Which also reminds me was there a large rubber "O" ring gasket at the base of the gas tank when you took off the fuel pump? I made the mistake and did not replace Mtnairlover's and boy it told it us right away something was not right as it leaked gas all over the drive where I live (the stain is still there, did not know gas stained asphalt). Any ? just PM or add to this I am not a pro but have messed up plaenty and I do lean from my mistakes.

Like Knuckle Dragger said, make sure the bolts are properly torqued. Too tight and you can deform the mounting surface/sealing area.

Actually, from what I could find, is this on an older Katana? And are you sure it's leaking from between the petcock and the tank, or could it be directly from the petcock? Might be rebuildable ...

its leaking from where the gas gauge mounts to the tank.... and yes its an older katana. and i'm positive thats where its from.

the bolts that i have to bolt it on are a bit stripped so i am getting new ones ASAP. hopefully that will fix the problem. i'm also going to try gold rated RTV like suggested above.
