Installing a fuel pressure gauge in your diesel truck gives you real-time visibility into what your fuel system is doing. Monitoring pressure while driving helps you catch issues early, protect your injection system, and keep your engine running at its best. Drops or fluctuations often point to clogged filters, weak lift pumps, or leaks. Catching those issues early can save you from expensive repairs and unnecessary downtime.
Included is the R7110-10 tubing kit for outside-cab installation only. For inside-cab installation, it's highly recommended to use the R7797-R fuel pressure isolator, which keeps fuel safely outside the cab while sending an accurate reading to the gauge. EV² gauges are built for accuracy, durability, and clear visibility. They feature a bright LED backlight, simple installation, and a front-sealed design with UV-stable outer housings to withstand harsh automotive environments.
Some Ford trucks from 1999–2007 may not work with the 1.7-volt gauge. Product documents are attached for your reference to check the voltage on your Ford. If your truck is not compatible, you can use an 8-volt gauge for your truck.
