Valid points from both of you. The reason for not replacing is I tried to remove the valves on a parts pump and could not get them out! The last thing I want to do is destroy this one. I will probably send it to Then and Now in the fall and I still have the NAPA unit that was working. That said, their new valves look very nice. I hope the NOS ones hold on for a few months.
