Gasket material for top of gas tank..

[N1VSM]

When replacing the cover holding the vent or pickup lines or the fuel sender in the gas tank, what type of gasket material (or goop) should be used?

I just had a brilliant idea! I'll go to NAPA and ask for gasket material that can withstand modern gasoline.

Good idea! I'd suggest either cork or neoprene, although paper is also good.

You might go and ask, but don't rely on that getting you the right material. Viton is the best, cork will work with gas, but is much more liable to crack or break at the screw holes when compressed. The best source I know for VITON rubber is McMaster-Carr, available in sheets of various thickness, even reinforced with fabric if you so desire, that's what we use. Never a failure thus far.

Doesn't Permatex make a sealer that works with gas? I'd just get some "form a gasket" and be done with it. Quick simple and if it's good enough for professional race cars it should be good enough for you and me.

I used Loctite 518 gasket eliminator.
