Re: Auxiliary Electric Fuel Pump

My understanding of the reason to mount an electric fuel pump close to the gas tank is that vapor locking occurs in the unpressurized part of the fuel system. The further back the electric pump, the more of the system that is pressurized. I don't know if they work better pushing or pulling, but the vapor locking in the unpressurized part of the system makes sense.

The electric pump on my '55 Clipper is mounted on the inside of the frame rail at the top of the arch above the rear axle. It is a Carter pulse type and works great for priming the system and over coming the occasional vapor locking.
