What Type of Sealant Should I use on my Fuel Line Fittings?
I was considering:
LA-CO 44094 Slic-Tite PTFE Gas Line Pipe Thread Tape, Premium Grade, [260" Length, 1/2" Wide], Yellow
but, I am now considering using this:
Permatex 80633 Thread Sealant with PTFE, 16 oz.
..or this:
Permatex High Performance Thread Sealant

Usually none of the above...
What exactly is the application?
I generally prefer anaerobic sealants vs. std pipe dope or tape.
On NPT threads I use Locktite anaerobic thread sealer w/Teflon, 565, 567 for high strength, available in many sizes, suggest mail order as local parts stores get stupid $$ for a 50ml tube.
This sets, and is rated for 10K psi.
It also works as a low-med strength thread locker.

Please define fittings?
On the solex straight/smooth barbs I favor rolling a file over the inserted end followed by a light smear of J-B weld over the new rough. From what I hear this is the same technology NASCAR uses on threaded fittings...yikes.

I decided on using this Millrose 70885 Monster Roll PTFE Thread Seal Tape
It is supposed to be gasoline resistant.
Also I plan to use a fuel filter between the fuel pressure regulator and the carb to catch any little pieces of the tape that could possibly clog up the carb.
