I would replace the complete pump to the newer part number, it will have the nylon impellar that will last much longer than the cast impellar did. typically a newer pump will wear out two discharge housings before the rest of the pump is worn out. after replacement the pump will need to be calibrated, the procedure is in the operators manual, if you have any questions just ask.
