I have a leak on the threaded fitting into the carb. I have tried tightening it to stop the leak and it successfully does, but only for a little while. By the end of a set it has loosened up or started leaking again.

Do these fittings have o rings or gaskets to help the seal? Or are these just tapered fittings that need some sort of thread seal like ptfe tape but fuel resistant?

Thanks for those of you that have the knowledge. I’ll be disassembling it this week to solve the problem.
