I agree, but before you shell anything out on a fuel pump make sure all the rubber in the fuel lines are free of cracks. I struggled with a 77 Bonneville that my father in law has that needed the carb to be primed if it had sat overnight. I put a fuel pump on it and it still wouldn't start without priming and would stall out once it ran out of fuel in the bowl. I put a vacuum gauge on the fuel pump inlet and it was pulling vacuum. So I jacked the car up and started putting an eye on the hose. Looking up from the tank forward over the rear axle was about 18" of rubber hose that was full of cracks and was extremely dry. Some new hose and one last prime and it was running like normal again.
