    I have noticed on my few small OMC motors that some have the small square pump and some have the larger one with five screws. How interchangeable are these?

    The small West Bend/Chrysler/Force pumps use diaphragm flaps for valves, are very simple, and seem to have worked for many years with the same design…..?

    True, some of those kind of pumps work ok. Chainsaws generally have flap valves but they only have to lift the fuel a couple of inches. OMC tried it twice that I know of, and both failed.
