Reply To: Mid fifties pressure tank rebuild problem

Also JohnRude, just an FYI, pressing the push button does not pump air into the tank. It pumps fuel up one side of the dual hose fuel line to the motor. Once the motor starts, crankcase pressure pushes air through the other side of the dual hose, originating at the manifold nipple, into the tank. The pressure accumulating in the tank then pushes fuel back up through the fuel line to the motor, and so on.
