Description
Monitor high-pressure fuel system performance with the AutoMeter 0–30,000 PSI fuel rail pressure gauge, designed for compatible 6.7L Cummins applications. Common-rail diesel engines rely on precise fuel pressure to support proper injection and consistent performance, making rail pressure an important parameter to watch on both stock and modified trucks. This compact 2-1/16-inch gauge gives you a clear, real-time view of fuel rail pressure, helping you keep track of system operation while towing, daily driving, or running increased power.
The gauge uses AutoMeter’s digital stepper-motor movement for smooth, responsive needle operation and performs a self-calibration sequence at startup to support accurate readings. It connects to the factory fuel rail pressure sensor wiring through the included harness, so high-pressure fuel does not need to be routed into the cab. Factory-matched LED through-the-dial lighting provides visibility at night and complements the original instrumentation. The gauge is compatible with 12- and 16-volt electrical systems and includes a wiring harness, mounting hardware, and installation instructions.
