Re: Help with hooking up an electric pump.

There is another way to install an electric fuel pump than those already described. This method involves installing the electric pump as close to the fuel tank as possible, and as already covered. Then, instead of tapping back into the fuel line in front of the pump, run another fuel line to the engine compartment. This line will terminate at the output side of the fuel pump. Install a "T" fitting so that the new fuel line can be connected here. Now you have the electric fuel pumped line bypassing the mechanical pump's line. The output valve in the fuel pump will only allow the electric pumped fuel to go one way. No need for a separate one-way valve. Also, should the mechanical pump fail, there would be no danger of pumping fuel into the crankcase. I believe this is considered to be a parallel system.
