Review on 🔍 8MILELAKE Engine Cylinder Oil Pressure Diagnostic Tester Tool Set: Accurate Diagnosis for Engine Oil Pressure Issues by Jim Martin

Connected but not reading. Disconnected the quick coupler from the adapter and oil squirted out so I knew there was some pressure. I removed everything, checked with compressed air - nothing legible. I connected the hose to the adapter and unscrewed the pressure gauge, the oil does not flow to the pressure gauge. Then, while testing with compressed air, I accidentally pressed the connector and the arrow moved. So I hooked the whole thing back up to the motor and when I pushed the quick connector I got a readout. Not an easy process as you have to press it while cranking the engine to check the pressure above idle and balance the gauge somewhere while the fitting gets HOT!
