Seems that I remember most of the early seventies models having a return line to the fuel tank. If the car has not been modified there should be a rigid fuel line secured to the frame near the passenger side upper control arm, that rigid line then has a flexible rubber line going to the fuel pump, directly next to that rigid line there should be another, smaller gauge rigid line, this would be for the return to the fuel tank. That should verify that you need the pump with the return, and where to connect it. If not, the car may have been modifed or I may be wrong, but at least that is something to check. About the carburetor seeming to get too much fuel, what do you mean? What happens? Does the carb have fuel spilling out from it? Is the engine running rich, bogging down, does it smell like gasoline? You might have something else causing your problem not related to the fuel pump because I would think that not having that return line connected to the tank would cause such troubles. I don't think you would want to use an electric if you are restoring the car anyway. Good luck, and let us know what is happening.
