MaxTow’s Black & Blue Double Vision™ Gauge Series features a black gauge dial and blue LED display with an illuminated red needle. You get the classic look of an analog gauge combined with a blue digital numerical readout. This 2-1/16” (52mm) gauge outperforms the competition with features like stepper motor technology which allows for all needle movement to be exceptionally smooth and all gauge readings to be extremely accurate. Brightness Recall remembers the previous brightness setting before powering down your truck.

This rail pressure gauge features extended wire harnesses for both sensor (9’) and power (5’) connections, ensuring you will have more than enough wiring for a quick and easy installation. The 9’ sensor harness connects directly to your truck’s factory rail PSI sensor wire for extremely accurate readings directly from the source. Easily attach both harnesses to the back of the gauge by utilizing seamless Plug and Play connectivity.

Why Do I Need A MaxTow Fuel Rail Pressure Gauge Kit?

MaxTow’s Fuel Rail Pressure Gauge connects to the rail pressure sensor, which is designed to monitor fuel pressure at the common rail. This diesel fuel rail pressure gauge gets its reading by wiring directly into the stock fuel rail sensor. The benefits of having a common rail diesel fuel system include that it offers higher performance, higher injection pressures, reduced emissions, improved fuel efficiency and more. Having a common rail pressure gauge also protects your diesel truck from potential engine harm.

MaxTow Common Rail Fuel Pressure Gauge Applications

When driving calls for more out of your Cummins or Duramax, a rail pressure gauge will keep you alerted to make sure your fuel rail pressure is where it needs to be. This gauge can be used to improve mileage or assess whether the filter or lift pump are starting to wear out. Since rail pressures typically run in the area of 27,000 PSI, MaxTow’s Duramax and Cummins rail pressure gauges are more than capable of covering the range. This gauge is only compatible with a 2003-2018 Dodge Ram with 5.9 Cummins and 6.7 Cummins Engines; and 2002-2018 Chevrolet Silverado and GMC Sierra trucks with a 6.6 Duramax Engine.
