FAQ:

Q: What to seal threads on gas line with?

A: Apply the gas-rated Teflon tape or pipe thread compound to the threaded end of the gas line in a clockwise direction. Thread the flexible gas hose fitting onto the threads. Then tighten the fitting using the pipe wrench, but don’t overtighten. Repeat the thread-sealing procedure for the gas line that comes from the dryer.

Q: Is diesel fuel cleaner than gasoline?

A: While it has been tested that diesel does burn cleaner than gasoline, there is still residual carbon deposited due to impurities in the diesel (go look up the chemistry of combustion).

Q: Is Permatex thread sealant gas resistant?

A: Permatex #1 & #2 form-a-gasket, and flexible thread sealant are all gasoline resitant. They do not have high adhesion though, they are just sealants that need varying amounts of time to cure. #1 is quick and dries relatively hard, #2 is slower and dries very flexible, threaded sealant never dries.

Q: What is the best thread sealant for gasoline?

A: For gasoline, regular old gasoline resistant Aviation Form-a-gasket Number 3 is the best option. Another product also offered by Permatex is the High Temperature Thread Sealant. Tech data on this sealant says it has medium solvent resistance and is recommended for fuel sender type applications.
