What kona said.
Where you put the Teflon tape does NO good. That stuff should be reserved at most for pipe threads, IF that.
I've NEVER used that stuff and have removed if from others oil and fuel pumps countless times.
It should be reserved for back most portion of the drawer of your tool box, and only there as a place holder for other stuff.
It's NEVER used in the military around AN fittings, it shouldn't be used around cars or bikes either.
IF...you feel the need for extra sealer, a "little" Teflon "paste" is a much better product, but again, only on pipe threads.
