Use of Teflon Tape on fuel fittings

Don''t do it!!! I just installed (then re-installed) a complete new fuel system on my 37'' sloop. Everything new, from the deck filler, right through to the lift pump on the 3GM30F, and new return lines as well.

I used teflon tape the first time through, I have some 1 1/2" npt bronze fittings going from the tank through a bulkhead to the fuel hose. Each one leaked just a drop when the system was filled for the first time.

I then had to drain the tank and take everything out, clean it, and re-assemble it all over again. This time I was using Teflon PIPE DOPE/JOINT COMPOUND, and my biggest stilson wrench to ensure that everything would be tight and leak free.

On pipes under 1 1/2", just coat the male threads and sock them down good and tight. On 1 1/2" and up, coat both male and female and tighten well. Be careful to not go overboard using too much pipe dope, as excess will clog up your first filter.

Good luck.
