Review on Reliable and Precise Standard Motor Products PS60 Oil Pressure Sender: Ensuring Optimal Engine Performance by Jerome Turner

As another customer of this product mentioned, the hex portion of the threaded fitting is stamped with the number 90. This is a 1/4 inch NPT fitting that fits my application but the oil pressure reading is not accurate at all. It shows about a quarter of what it should read. At this point the pressure sensor is only acting as a stop leak fix until I buy a better quality transmitter. Definitely disappointed.
