I had one on My 40 Pickup for years (remove or cut 1" off top of push rod ) ran through mechanical pump to keep engine looks-some say it acts as a pressure regulator?? Recommend hook up pump on switch seperate of ignition so you can shut off & run Carb dry for short or long storage. My 36 will get same treatment for florida heat--Also sent Coil & Water Pumps to "Skip" for same reason. The pump I use is the Airtec E8902 6v-delivers 3.5-4 psi Good luck
Ken, A bellows type pump has two one way valves:
The inlet valve allows the bellows to push fuel into the chamber. The outlet valve allows the chamber to dump to the carburetor. There is no pressure regulating action between the two valves. The spring that pushes the bellows limits pressure built by the mechanical pump, but has no limiting effect on fuel pushed through the pump.
