    i have recently put a 78 350 in an 88 Silverado. Still working out the kinks. I am running a mechanical pump on the engine and cannot draw fuel from the tank through the electric pump. Could I run off the original return line to pick up fuel?

    You could run the stock electric pump with a regulator.

    I don't know the sizes of the stock inlet outlet fuel lines of the TBI GMT400 trucks.
