Bob Aller told me how to build a oil pump pressure tester out of aluminum plate. You cut a piece to fit over the output of the pump. You drill and tap for a gauge in the output , and put the pump on a drill.

You can test with oil above and below the area where the shaft enters the casting. The area where the air enters the pump if not bushed.
