I used some teflon/PTFE paste that is designed for fuel/oil/diesel but I think tape would work too. The threads are very tight so be careful.I am going to replace my factory plastic fuel line couplings with the nice stainless pieces. My question is do you use any thread sealant such as teflon tape, theadlocker, etc when fitting the couplings?
Don't have a pic but they are identical in appearance to the plastic ones (other than being shiny metal), same manufacturer (cpc) and all.Does anyone have a pic of the quick disconnects installed? That would be helpful.
NOTE: the fittings to the tank side do not go as deep as the plastic ones. I used threadlocker to seal them.
