MaxTow's White Face Double VisionTM Series 30,000 PSI Fuel Rail Pressure Gauge is compatible with the 03-08 Dodge Ram with 5.9 or 6.7 Cummins engine, as well as the 02-08 Chevy and GM with 6.6 Duramax engine. This diesel fuel rail pressure gauge reads your truck's high fuel pressure levels from 0 - 30,000 PSI directly from the common rail, allowing you to monitor your Cummins or Duramax engine with unrivaled accuracy, while protecting against damage to your fuel pump, injectors and a loss of overall horsepower.

MaxTow's Double Vision Gauge Series features a green digital LED display, as well as an illuminated red needle, which will give you the classic look of an analog gauge while also giving you an easy to read green LED numerical readout. This 2 1/16 inch (52mm) 30,000 PSI fuel rail pressure gauge features stepper motor technology which allows for all needle movement to be exceptionally smooth and all gauge readings to be incredibly accurate, ensuring your truck's vital parts are functioning properly. Our diesel fuel pressure gauge also features innovative daytime and nighttime dimming modes with three customizable brightness settings (low, medium, high) for each mode.

MaxTow's Rail Pressure Gauge features extended wire harnesses for both power (3 ft.) and sensor wire (9 ft.) connections, ensuring that you will have more than enough wire for a quick and easy installation. The 9 ft. sensor harness connects directly to your truck's factory rail PSI sensor wire for extremely accurate readings directly from the source. All gauge mounting hardware and installation instructions come standard with every diesel rail pressure gauge purchased, as well as free lifetime technical support and a one year limited warranty.
