HOW TO USE:
- Mount the Gauge: Choose a suitable location on your dashboard or instrument panel and create a 2.67″ (68mm) diameter hole. Secure the gauge in the opening.
- Install the Pressure Sensor: Locate an appropriate port on your vehicle’s fuel system. Install the included 100 PSI pressure sensor (using the 1/8″ NPT thread) at this location. Ensure a proper seal to prevent leaks.
- Connect the Sensor Wiring: Connect the 3-wire cable from the pressure gauge to the corresponding terminals on the pressure sensor. Refer to the wiring diagram provided with the gauge or on Speedhut’s website for correct connections.
- Connect Power and Lighting: Connect the 3 ft power & lighting harness. Typically, one wire will connect to a 12V power source (ignition switched is recommended), and another wire will connect to a ground. The remaining wire(s) are for the LED illumination and should be connected to a 12V lighting circuit (e.g., your vehicle’s headlight or parking light circuit) to illuminate the gauge when the lights are on.
- Ground the Gauge: Ensure the gauge housing has a proper ground connection to the vehicle’s chassis for accurate readings and proper operation of the electronics.
- Verify Operation: Once all connections are made, start your vehicle and check the fuel pressure reading on the gauge. Turn on your vehicle’s lights to ensure the gauge illumination is working correctly.
