Editing Mounting an electric fuel pump

If you solid-mount the pump (bolt it directly to a frame member or other suitable structure of the car), it will transmit the noise and vibrations made by the pump into the sheet metal of the car and make a pretty good racket that gets old to your ears after a while. When I mount one, I stop by Pep Boys or other automotive outlet and get some muffler/exhaust pipe hangers. These are black rubber hangers that are about 3/4 inch thick and 1inch wide and look like they may have been cut from an old truck tire. They have holes drilled in them along the length and a quarter-round metal piece riveted onto one end of the hanger that matches the exhaust pipe curvature. I cut the metal piece off and bolt a couple of hangers to the car and then bolt the pump to the hangers to isolate the noise. I also use barbed fittings for the fuel in/out at the pump and use a 2-3 inch piece of fuel-rated rubber hose to attach the inlet and outlet hard lines to the pump to further isolate the noise and vibration produced by the pump. It's also a good idea to mount a fuel filter between the tank and the pump to keep junk out of the pump. Mount the pump as low and as near to the tank as possible without putting it so low that it would get hooked on highway trash and leave you thumbin' for a ride home. Electric pumps were designed to push fuel, not pull it.
