You could try the library for a manual.And if you expect to be doing work on your motor you should have a service manual.I don't know your pump but the operation is no mystery.One port is for the pulse that moves the diaphram and a gas in and gas out port.valves are installed so gas can flow only in the in and out the out port.There may be 2 springs on either side of the diaphram the longer one goes toward the valve body on some pumps.and the shorter one goes
on the side of the diaphram toward the cover.
