Oil Pressure Sensor (OPS). Direct replacement for you old OPS. If your Lift pump/fuel pump has failed then there is a good chance the problem is a burnt out OPS. The OPS send 12 volts to the lift pump and also a signal to your oil pressure gauge. So the gauge may work but the lift pump may not.
I would recomend using a LP relay harness to take the load off your OPS and the inadequate wiring system used on the GMT-400 trucks.
