Description
Keep your Cummins fuel system in check with the AutoMeter 0–30,000 PSI fuel rail pressure gauge, designed for compatible 6.7L Cummins common-rail diesel applications. Monitoring rail pressure helps you track fuel system performance and spot pressure changes that could affect fueling consistency, particularly when towing, daily driving, or running performance upgrades. The compact 2-1/16-inch display provides a clear, real-time pressure reading, giving you useful insight into fuel system operation without taking up excessive dashboard space.
This electronic gauge uses AutoMeter’s digital stepper-motor movement for smooth, responsive needle operation and a startup self-calibration sequence. It monitors pressure through the factory fuel rail pressure sensor’s electrical signal, eliminating the need to route high-pressure fuel into the cab. Illuminated dial styling supports visibility at night, and the gauge is compatible with 12- and 16-volt electrical systems.
