Vacuum pump

[Dale Campbell]

I had my mechanic remove old pump and the plastic coupling was sheared. My ship has de-ice boots so the company with the new style piston pump told me they do not have a pump that will work on planes with boots. So I ordered a new dry pump. That should be in this week. If anyone has a 337 without de-ice boots that new piston pump looks good. The factory told me they have one running on a test bed for 20,000 hours and it did not fail yet. Dale Campbell
