Replacement pump well packaged and now working to specification. Maybe I missed the information in the listing but suggest you state that the overhauled pump comes with gasket and O-rings. I ordered an extra pump to accessory case gasket.

Installed on an M20-j. Pressure is right on the redline for the airframe. It’s well within specs for the engine. Worked as expected.
