When my pump leaked I replaced it with the 4088 pump. While waiting for it to come in I took it apart and cleaned the diaphragm and put silicone adhesive at the parting line that stopped the leak. I tried just cleaning it and retorqueing the bolts but that did not not stop the leak. I would try the silicone adhesive first before ordering a new pump.
