      Comments about Melling Stock Replacement Oil Pump:

      When I replaced my engine I figured it would be a good idea to replace the oil pump. I would also recommend replacing the pick up and the oil pump shaft with the metal collar. The is one comes with the plastic collar that is prone to breaking and causing a loss of oil pressure.
