MaxTow’s White & Blue Double Vision™ Series 30,000 PSI Fuel Rail Pressure Gauge is compatible with the 03-18 Dodge Ram with 5.9L or 6.7L Cummins engine, as well as the 02-18 Chevrolet and GM with 6.6L 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 blue LED display and an illuminated red needle, which gives you the classic look of an analog gauge, as well as an easy to read digital numerical readout providing you with multiple options and added convenience when reading the output of your diesel truck gauge! This 2 1/16" (52mm) rail pressure gauge outperforms the competition by featuring stepper motor technology that allows for exceptionally smooth needle movement and extremely precise gauge readings. No matter how much your truck is shaking or pulling, the needle stays unaffected and delivers the accurate results you’re looking for in a reliable gauge. The three daytime brightness settings (d1, d2, d3) allow you to easily view your gauge readings without being affected by the sunlight, while the three nighttime brightness settings (n1,n2,n3) allow up to a 50% dimmer glow for easier viewing at night! The included brightness recall function remembers the previous brightness setting you had on before powering the truck down, so you won’t have to set it every time you power your truck back on.

MaxTow’s Rail Pressure Gauge features extended wire harnesses for both power (5') and sensor wire (9') connections, ensuring that you will have more than enough wire 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. 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. Get ready to hit the road and Tow to the Max™!

Adding MaxTow'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 source. This rail pressure harness features a length of 6" with 9" sensor and ground lead wires.
