My son has resently purchased a 1970 cutlass and is currently restoring it.This is new territory for us and we need some info about fuel pumps. When he bought the car the fuel pump on it leaked out of the hole that is in it so he replaced it with a new one. The original one did not have a return line on it but the new one does, and we were told to just plug it,so we did but the car seemed to be getting too much gas so we rebuilt the carb(2bl) and it didn't seem to change anything. It was suggested to us that the pump with the return line might be pushing too much pressure and changing to an electric fuel pump would solve the problem but we don't know what pressure the pump should be putting out so we don't know which one to put on. Any info on this would be greatly appreciated.
