quote amuller:
and forgetting about the pulsation damper and diaphragm spring, should yield a pump that pumps–assuming that the inlet and outlet valves are properly assembled. Thoughts?
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.
I am no fuel pump expert but I would try and come as close to the original design/intent by using all the the springs including the center spring capped with a small metal or plastic disc that will contact the diaphragm. This is how I’ve done a few of them and have had no problem.
