My statemant was confusing.
I meant to say that some suggest that zero sealant is suitable for the threaded fittings but when the assembly is filled with gasoline the petro seeps through the threads.
My conlusion, at this point because so many here are uncertain, is that a sealant is needed.
You say "heat is the sealant"
Don't we heat tight connections to get them loose?
