Got a 5/16 fuelflex line I need to tie into an M14 x 1.5 fitting, this the right adapter to make that happen?

Yeah, that's exactly what the FL12-14MM is built for. One end connects to a 5/16-inch Fuelflex line and the other steps up to an M14 x 1.5 thread. The flared tube design handles the sealing side of things, so you're not relying on tape or extra fittings to keep it from weeping. Brakequip makes it for hydraulic and fuel fluid applications, so it's meant to hold up in working conditions, not just sit on a shelf looking good.
