Did you bypass the existing fuel pump? It also sounds like you got the wrong pump, you need a pump that has a pressure sensing unit built in it, so it turns off when fuel pressure max is reached and then only runs just enough to maintain it, otherwise you will need to use a return system on the fuel lines so the fuel is returned to the tank after the float in the carb shuts the fuel off, otherwise it is possible for the pump to lift open the needle and cause excessive fuel flow and could cause flooding or rich running. Most pumps use a 15 amp fuse wired to a key switched power source.
