I am redoing the seal on the fuel system and was wondering what the correct sealant to use on the NPT threads in the fuel filter housing. Liquid teflon pipe sealant or what?
I like using teflon tape but only use enough to wrap the threads 1&1/2 times.
Never use Teflon tape on the fuel system. The smallest piece can easily break off causing a restriction. I suggest Permatex® High Performance Thread Sealant

+1 there, No tape on fuel OR hydraulics, use a liquid teflon sealant. I use both loctite and permatex brands.
X 2 for that one, I have used that particular sealant for many years on may things including "Core/frost plugs" fuel fittings, coolant fittings, just bout everything.
Animal.. If teflon tape didn't seal the pipe fittings you post about then they were not made correctly..... But if you feel more is better thats fine with me. Its happened to me also but these fittings sometimes are made offshore and are suspect at best. Its just a hit and miss thing sometimes.
I put in a water line and had 2 brass fittings and I ran out of thread tape after almost 2 wraps but I wanted to get it done so I put it together and ended up having to go back and take it apart cleaned the old tape off and rewrapped it and no more leak so never again will I skimp on the tape for a few cents
