The Classic Fuel Pressure Gauge gives you a clean, reliable way to monitor low-pressure fuel systems. Built with a 0–30 PSI range and matched pressure transducer, it delivers accurate fuel pressure readings without running fuel lines into the cabin. A precision stepper motor keeps pointer movement smooth, stable, and easy to read, while the internal microprocessor, slim case, spin-lock mounting ring, solid aluminum bezel, and weather-resistant construction make it ready for street, track, and performance builds. Made in the USA and backed for life.

Track-Tested. USA-Built. Backed for Life.

Every Speedhut gauge includes a lifetime warranty* on the electronic circuit board inside the gauge case. It is the core of the gauge — the part responsible for the precision communication that delivers the accuracy and performance Speedhut is known for.

Sensors, wiring, and other external components are covered by an unlimited 5-year warranty.

This combined lifetime / 5-year warranty applies to the original purchaser.
*For your lifetime — as long as you own the gauge — we stand behind it.
Speedhut Inc warrants products to be free from defects in materials or workmanship. This warranty is limited to repair or replacement. Speedhut Inc is not responsible for incidental or consequential damages. Improper use, installation, or unauthorized modifications void this warranty.


Ensure you are using our sensor, most other sensors will not work with our gauges.


With the harness disconnected from the sensor and the gauge powered on, measure the voltage across the red and black wires in the harness at the sensor end. Here you should see 4.9-5 volts. 


Once you have confirmed the voltage, short the red wire to the white wire, this should make the gauge sweep full scale. 


With the harness still disconnected from the sensor, go to key-on or start the car. With the sensor disconnected the gauge should stay at 0 or the bottom of the scale.


If all those turn out normally, next we'll test the sensor. Disconnect the harness from the gauge, and reconnect it to the sensor. Measure voltage between the white wire (signal from sensor) and black wire (ground) and you should see a range between 0.5 to 4.5 volts. You will need to supply power and ground to the sensor while it's disconnected from the gauge. You can use short paperclip pieces if needed.

Our fuel pressure gauge isolates the fuel at the sender and does not enter the vehicle. You will not need a fuel pressure isolator to run our gauge. The wire harness and sender are included with the gauge.
