RTV and Ultra RTV silicone sealers (room temperature vulcanizing, i.e., the temperature when the silicone begins to set up) work in situations up to 750 degrees Fahrenheit. You can find these in multiple colors and in various depending modes: aerosol cans, tubes, and caulk-gun style cartridges. The color of the sealer indicates heat tolerance. Gray, black, and blue are for up to 500 degrees; red and orange are for up to 650 degrees, and copper is for up to 750 degrees. Experts recommend using the Ultra version for the current electronically-controlled vehicles because they are safe for sensors. [links]

Just don't crank it up so tight that you split a fitting.
With Never-Seize and Teflon tape, friction is lessened and it's easy to overtorque fittings.
Point 1: Many of the most popular fuel pumps have NPT fittings on the inlet and outlet. If you use the appropriate fittings and don't use sealant, you will have leaks.
Point 2: Tape is like anything else, including the teflon sealant. If you use it correctly, it works. If you don't, it causes problems. Sure, a piece of tape in the line can plug things up. So can a glob of anything else. "Havoc" isn't unique to teflon tape.
Loctite's LPT I think it's called, works fine on steel and brass. here
Don't use it on aluminum.
It glues the aluminum together so strongly that you'll peel threads off the male fitting when taking them apart later on.
And later on can be ten minutes to several months. here
That said, the local speed shop recommended Never-Seize for use on pipe threads that are aluminum on both sides.
It works well.
