Re: Early OMC fuel pump

[amuller]

I finally cut a diaphragm and put it together. No difficulty making the dia. from material from McMaster-Carr. I just made it plain, ignoring the spring and its centering piece riveted into the dia. I think it will pump OK but we shall see.

The real difficulty was getting the pump together with the valves working. What finally worked was to leave the screws a bit loose and thump on the pump with a screwdriver handle.
