Brass fuel fitting sealer?
Is there ANYTHING to use to seal brass fuel line fittings? I dont recall ever using anything, but the elbow fitting on my fuel pump has a very slight leak, and tightening it further will turn it too far to connect the fuel line (without further mod)...maybe a tape or a Permatex-type product??
Thanks...

It's okay to use if you're very careful that none of the tape strands are actually IN the gas flow. If it gets into the gas it can clog fuel filters.
Teflon paste might be a little easier, but tape will work if you're careful it's neatly wrapped around the threads and not in the fuel path.

Teflon Tape sucks only good for water pipes. The strands will get into the carb inlet filter. Use the paste.

I just thought of another good sealer Blue lock tight. I use it to seal up helium leaks in brass fittings all the time at work. You can still get the fitting apart with no problem. Just make sure you let it dry before putting it to the test. I haven’t had much luck with the paste for pipefittings, I’m sure it works well just not for me.

The threads aren't the problem. The fuel line uses inverted flare fittings if you are leaking gas it is from the flare, the threads only press the two ends together to make the seal. I would look at the mating surface and see if there is a crack.

I guess this looks familiar.
You can use teflon tape with no future leaks.
Leave the first thread bare so there is no chance it gets into the carb filter and wrap no more than 4 times. When tightening, don't back up.
