HOW TO IDENTIFY EARLY VS LATE DI FUEL RAIL PRESSURE SENSORS
- Proper sensor identification is critical when selecting any EFI system –
- There are two different fuel pressure sensors that GM uses with the Gen V LTx engines. Depending on which one your engine has will determine which kit/harness is required. The Sensor is mounted to the back of the driver side fuel rail (as shown below). Compare your sensor to the pictures above to determine if you have an early or late sensor.
