what is everyone using to seal threads for diesel fuel when running the big line kit at the holley pump and any misc places that need it?

I didn't use any thread sealant at all... No leaks either...

I'm rather a bit timid of putt anything on the threads of a fuel system that might get suck in the fuel system.

thanks guys. it's all on and done. But from adding the big line kit I lost about 2 psi at wot. what size diameter are the little washers so I know what will fit in there I don't have any that small to shim my holley to create more pressure.
