I'm not familiar with the mercruiser 470 but it seems like you could just leave the mech. pump bolted to the engine so you wont be left with a hole, and just hook the lines together at the original pump and put an electric pump in-line somewhere. You would have to make sure the electric pump delivered the right pressure, carburated engines only need a few psi. But why not just replace the original pump and save the headache?
