"Plumber's tape" is the perforated steel strap used to hang pipes.

Teflon thread sealing tape has no place at all on brake line or fuel fittings, which seal at the flare, not the threads. If a pipe-to-flare adapter fitting is used, I'll use paste-type pipe joint compound on occasion, but it the fitting is brass, it's usually better to install it dry, or maybe with a very sparing application of brush-on Permatex sealer like Super 300 to the pipe threads only.
