Adding a Fuel Rail Pressure Gauge to your truck?

If you’re driving an 03-11 5.9L or 6.7L Cummins or 01-12 Duramax LB7, LLY, LBZ, or LLM truck, using a MaxTow Fuel Rail Pressure Gauge Pigtail Wiring Harness will simplify the install. The Fuel Rail Pressure Harness installs directly to the fuel rail pressure sensor without having to splice into factory wiring.

To install, simply disconnect the rail pressure harness connector and plug the new fuel rail pressure pigtail harness into the factory sensor and sensor harness. Finish by connecting the green and black wires from the gauge harness to the matching wires on the pigtail rail pressure harness. This rail pressure harness adapter is 6” in length and features 9” sensor and ground lead wires.

MaxTow 30,000 PSI Fuel Rail Pressure Gauges read your truck’s high fuel pressure levels directly from the common rail to monitor your Cummins or Duramax engine with unrivaled accuracy. At the same time, you’ll be able to help protect against damage to the fuel pump, injectors, or a loss of overall horsepower.

These Double Vision™ truck gauges are available with a Black Gauge Dial or White Gauge Dial, featuring an illuminated red needle and green LED display while also delivering an easy to read green digital numerical readout.

MaxTow includes Installation Instructions with every purchase, Free Lifetime Tech Support and a One Year Limited Warranty.
