Good Morning,
Any opinion on thread sealant for gasoline fittings. I have used blue locktitie,242,without to much problem. I rebuild carburetors for air cooled engines every day and most manufactures use a sealant that looks like varnish? Obviously, not what it is, but I still dont know what it is. I use an ultrasonic cleaner and special water base soap and this removes the oem sealant and all old fuel deposits. Loctite is a little hard on removal of brass fittings but works.

Brass fittings require no sealant when new. Steel, yes. It should get a light application of plumbers putty sealant or, next best is teflon tape. Properly made double flare fittings require no sealant.

OK, Oops, Im sorry I posted this thread on the wrong forum. Trouble is that virtually all of the threaded fuel parts we deal with on these jeeps are used. Maybe with the exception of new fuel line fittings as they indeed are flared fittings. The brass elbows on the carb body and fuel pump body is where my inquiry was directed to. Even using new brass elbows, installed in previous used bodies capillary leaks occur. This ethanol fuel sucks! Seems to attack everything it contacts after some expose time. I see a product, Aviation gasket sealant #3, is supposed to be resistant to this fuel contact. Anyone try it? Guess Ill give it a go and see how it holds up. I'll let you know. Thanks

Give Teflon Tape a try. Use only two wraps and keep it out of the bore of the fitting.
