I am trying to keep the Onan original, and the fuel pump out of the landfill.

Terry Taylor took a shot at 3d printing the nylon Spring Cup Valve but I couldn't measure the dimensions close enough and the printed part won't work.

If anyone has rat holed an old Onan fuel pump in the hopes that some day it might come in handy, this might be it. I can buy the cover gasket online, but nobody has the Spring Cup and Valve. I don't need the whole pump, but if it saves the hassle of dismantling it, I will gladly take the whole thing. If it is already apart, I need the parts shown here:

At the very least, I would like the Spring Cup and Valve. No heroic measures and not worth a lot of dollars to me. I do have a backup plan.

There was no file attached. If you attached it, the interweb stole it.

Pm me an address. I have mine sitting in the garage looking for a new home. It's complete and not being used.
