Description
Keep a close eye on fuel rail pressure with the AutoMeter 0–30,000 PSI electronic gauge, designed for Ram trucks with the 5.9L Cummins. High-pressure common-rail fuel systems rely on precise pressure control to support consistent fueling and engine performance, making rail pressure an important parameter to monitor on stock and modified trucks. This gauge provides a clear, real-time pressure reading in a compact 2-1/16-inch format, helping you keep track of fuel system operation while driving, towing, or putting your Cummins to work.
The gauge uses AutoMeter’s digital stepper-motor movement for smooth, responsive needle operation and performs a self-calibration sequence at startup to help maintain reading accuracy. It connects to the factory fuel rail pressure sensor wiring through the included harness, avoiding the need to route high-pressure fuel into the cab. The design features a factory-matched illuminated dial, compatibility with 12- and 16-volt electrical systems, and includes mounting hardware and installation instructions.
