Are the gasket surfaces flat and seating well? Is the inlet valve installed correctly or freely opening. Assuming all else installed correctly, the only thing I could see happening is gas is not free to enter the pump or diaphragm chamber and it is trying to pull from somewhere else. Sometimes the short rubber hose between steel line and pump deteriorates to the point where the inside collapses and no gas can flow thru. Must say though, I've never seen a pump with that much strength to be able to pull a gasket.
