30 PSI Fuel Pressure Gauge; Tinted 7 Color (Universal; Some Adaptation May Be Required)

High-Precision Fuel Monitoring. The 30 PSI Fuel Pressure Gauge with Tinted 7-Color LED backlighting is designed to accurately monitor fuel pressure in diesel trucks using low-pressure systems, displaying readings from 0 to 30 PSI. This gauge helps maintain vehicle fuel pressure within optimal levels, preventing damage to fuel pumps or injectors and avoiding horsepower loss. It is ideal for upgrading factory gauges or adding real-time fuel pressure monitoring to diesel vehicles.

Construction and Appearance. Featuring a durable black face and a tinted, low-profile magnified lens, this fuel pressure gauge enhances readability. The needle is illuminated red and sweeps 270 degrees with smooth, accurate movement enabled by advanced stepper motor technology. The ultra-bright LED backlighting offers seven solid colors, allowing customization of the display to match interior lighting or improve visibility. The color memory function retains the chosen backlight color after vehicle shutdown.

Installation. Installation is straightforward with included wiring harnesses and mounting hardware, requiring only standard automotive tools. The sensor installs directly into the fuel system using 1/8-27 NPT male threads, and no drilling is generally necessary. Some applications may require a thread adapter. The gauge’s backlighting can be dimmed by 30% when connected to the factory headlight switch.

Warranty. The product comes with a one-year limited warranty covering manufacturing defects and performance reliability.

Application. This gauge fits universal applications, though some adaptation may be required for specific vehicle fuel systems. Notable considerations include the need for a snubber valve on Dodge Ram Cummins trucks to prevent sensor damage and an aftermarket lift pump to ensure compatibility with GM Duramax engines.
