GlowShift’s Black 7 Color Series 30,000 PSI Fuel Rail Pressure Gauge reads Dodge, Chevy and GMC diesel truck fuel pressures directly from the common rail, allowing you to easily monitor Cummins or Duramax engine rail pressure levels. Please note that this gauge is only compatible with the 2003-2018 Dodge Ram featuring a 5.9L or 6.7L Cummins, and the 2002-2018 Chevy Silverado or GMC Sierra with a 6.6L Duramax. Installing this gauge will ensure that your diesel truck is running at optimal levels, which will protect against damage to injectors as well as a loss of overall horsepower. This 30,000 PSI fuel rail pressure gauge also includes a color coded wire harness that allows you to connect the gauge directly to your truck’s factory rail PSI sensor signal wire.
The Black 7 Color Gauge Series
GlowShift’s Black 7 Color Gauge Series comes standard with incredible features including a black gauge face, magnified clear lens, and an illuminated red needle that sweeps 270° and utilizes stepper motor technology which enables extremely smooth needle movement. The Black 7 Color Gauge Series includes the ultra-bright LED solid color modes Blue, Green, Red, Teal, Yellow, Purple and White. Also included is GlowShift’s 7 Color Lighting System which allows you to select and change the color of your gauge lighting display by simply pressing the button located along the front of the gauge. With the 7 Solid Color Settings and 2 Color Cycle Modes that utilize every dynamic LED color, you can customize the look of this Diesel Fuel Rail Pressure Gauge and add your own personal touch and style to the inside of your vehicle. Plus with the Color Memory option, you won’t have to reset the color of your gauge every time you turn on your vehicle. Your gauge will reflect your most recent color setting the next time it is active. By connecting the orange wire of your gauge to the factory headlight switch, you’ll be able to dim the gauge 30% when your headlights are turned on to reduce brightness while driving at night.
Why Do I Need A Rail Pressure Gauge?
GlowShift’s Fuel Rail Pressure Gauge works in tandem with the rail pressure sensor, which is most often found on the common rail and is designed to monitor the fuel pressure that is present at the common rail. The diesel fuel rail pressure gauge gets its reading by wiring directly into this stock fuel rail sensor. While this gauge pulls readings directly from the common rail, 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 harm to your engine. Low fuel rail pressure readings can be an indicator of a weak or bad injection pump, and this gauge’s readings will alert you when your diesel engine either requires more fuel or when it is running at optimal levels.
Rail Pressure Gauge Applications
A common rail fuel pressure gauge can be useful for several different reasons when added to your Dodge or Chevy. In applications that call for more out of your Cummins or Duramax, such as driving long distances or towing heavy loads, this gauge will keep you alerted to make sure your fuel rail pressure is where it needs to be. Not only can monitoring rail pressure help you in determining if pressure levels are running too low or excessively high, but these readouts will also help in diagnosing hard starts, rail depletion, or a leaking rail. They can even 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 approximately 27,000 PSI, this gauge is more than capable of sufficiently covering your range.
Add-On Pigtail Wiring Harness
Adding GlowShift’s Fuel Rail Pressure Gauge Wiring Pigtail Harness eliminates the need to splice into any factory wiring to receive rail pressure readings. This gauge harness installs directly to the rail pressure sensor for extremely accurate readings directly from the common rail. The harness features a length of 6” with 9” sensor and ground lead wires.
