OIL PUMP PRESSURE TESTER
When modifying oil pumps for max relief pressure, it can be a crapshoot until the engine is running. This is one of my 50-year-old test units manufactured essentially from spare parts. A main cap, pressure gauge, and a sealable container. (To eliminate contamination while being stored). Install oil, pump, prime, and drive with electric drill. This allows testing and correction prior to installation.
