My Q-Jet on my LG4 was stripped at the fuel inlet nut, so I installed a self-tapping nut. Only problem is that the original nut was designed to seal internally and the new nut has an external gasket. This gasket will NOT seal against the thin outside edge of the fuel inlet. I tried a Buna N70 O-Ring along with the gasket...that held for a little while and then started leaking again.
My question is...what material is suitable for sealing this? I was told I could use RTV Hi-Temp silicone, but it says on the back of the package that it's not for use with gasoline-immersed parts. I could just use some epoxy but I don't want to make this permanent if not absolutely necessary. Right now I'm using some Gasoila thread sealer to make the seal...it says it's insoluble in gasoline, but I don't know how it'll work. If anyone has any suggestions of a type of gasket or gasket-forming substance that'll resist constant gasoline immersion, if you could tell me where to find it, I'd greatly appreciate it.
