Rail Pressure Gauge for 4th Gen Dodge Trucks

If you're pushing serious power out of your 2009–2018 Ram 2500 or 3500 with a 6.7L Cummins, keeping an eye on rail pressure isn't optional, it’s essential. The AutoMeter Factory Match Rail Pressure Gauge is built to give you a reliable window into what’s happening at the heart of your fuel system. With a full sweep range of 0 to 30,000 PSI, this gauge delivers the pinpoint accuracy diesel performance demands, especially on modified trucks running higher-than-stock fuel pressures. What sets this gauge apart is its advanced digital stepper motor movement. That means smoother pointer response, no needle bounce, and dead-on readings every time. It plugs directly into your factory rail pressure sensor using the included harness, so there’s no need for messy extra wiring or fluid lines inside the cab. The factory-matched LED backlighting blends right in with your OEM cluster, offering clean nighttime visibility without drawing unwanted attention.
