Re: fuel pluming help
The extra outlet on your pump should be about 1/4" in diameter and is intended as a return to your tank. The tank sending unit should have a dual line setup on the sending unit for the return line to route to. In effect you should have two gas lines running from the tank to the fuel pump, (the smaller one is a return line).
