Rail Pressure Gauges

MaxTow Double Vision 30,000 PSI Fuel Rail Pressure Gauge reads your truck’s high fuel pressure levels directly from the common rail to allow you to monitor your Cummins or Duramax engine with unrivaled accuracy, while protecting against damage to your fuel pump, injectors, or a loss of overall horsepower. The MaxTow 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.

Max Tow’s Rail Pressure Gauge features extended wire harnesses for power (3ft) and sensor wire (9ft) connections, to ensure that you will have more than enough wire for an easy installation. The sensor harness connects directly to the factory rail PSI sensor wire for accurate readings directly from the source. All mounting hardware and installation instructions are included with every diesel rail pressure gauge purchase, along with a one year limited warranty and free lifetime technical support. Get ready to hit the road and Tow to the Max.
