I am going through a 5.5 Oliver that hasn’t run in years. The fuel pump was leaking, so I took the cover off. There was only a diaphragm between the two halves, no check valves, springs, etc. What all am I missing?
I believe the diaphragm itself acts as the check valves. I had the same question when I fixed mine!

Thanks for the info. Seemed too simple to be right compared to any other pump I’ve had apart.
