Installing a Fuel Rail Pressure Gauge into your Dodge Ram, GMC Sierra or Chevy Silverado? If you’re driving a 2003-2018 Dodge Ram 5.9 or 6.7 Cummins, 2002-2018 Chevy Silverado or GMC Sierra 6.6 Duramax LB7, LLY, LBZ or LLM, using our Fuel Rail Pressure Gauge Wiring Harness will make the install even quicker and easier. This wiring kit installs directly to the fuel rail pressure sensor without having to splice into factory wiring or make any other major modificaations.
Simply disconnect the rail pressure harness connector and plug the new Fuel Rail Pressure Pigtail Harness into the factory sensor and the sensor harness. Connect the green and black wires from the gauge harness to the matching wires on the pigtail rail pressure harness. The rail pressure harness adapter is 6” in length and features 9” sensor and ground lead wires.
GlowShift Fuel Rail Pressure Gauges are available in our 7 Color Series featuring Tinted 7 Color, Black 7 Color or White 7 Color versions. Choose between a black or white gauge dial, clear or tinted magnified lens, and 7 color options for the analog LED display with an illuminated red needle.
This gauge is also available in the MaxTow Double Vision™ Truck Gauge Series which has a dual analog and digital LED display. Choose between a black or white gauge dial and green or blue LED display. There are also 3 Daytime and 3 Nighttime Dimming Modes to adjust the gauge brightness anytime you’re driving.
Using this Fuel Rail Pressure Gauge Wiring Harness, the gauge will read your diesel truck’s fuel pressure directly from the common rail so you can easily monitor your Cummins or Duramax diesel engine’s fuel pressure. Benefits include helping to ensure that your engine’s fuel pressure is running at optimal levels which in-turn protects against damage to the fuel pump and injectors.
