Re: 6v fuel pump wiring question

My '50 came with an electric fuel pump wired directly to the coil (always on when the engine was running). I re-wired it to the ignition switch with a 3-way marine switch hidden under the dash (off, on, spring-loaded manual hold-on). The pump is simply cut into the existing fuel line, attached back by the tank with no pressure regulator. I frankly don't know why the former owner installed it. The car starts and runs just fine without it being on. Maybe he had vapor lock problems... I don't (I use real gasoline for my Packards, no alcohol). I have used it to prime the carburetor after the car has been sitting for some time but it really doesn't take that much cranking to get the engine to start on its own.

My '49 doesn't have one and, at present, I don't see a need to install one.

My '41 has one but that car is a work in progress and I don't know the status of the mechanical fuel pump yet.
