That's fine for gasoline engines but many large diesels and their

mechanics routinely use something like blue Permatex goop to seal the

Right - standard pipe threads, and this is the off-engine plumbing - fuel
transfer between tanks, etc.

Previously, I was using a teflon-based paste of some sort, but my supply is
long gone and I no longer remember what it was called or where I got it.
Hence my request for suggestions.
