Take preventative measures by installing an EV2 fuel pressure gauge that monitors how hard your fuel pump is pushing fuel toward your engine. Your diesel engine must get the right amount of pressure for the injectors to work correctly. If the pressure fluctuates, it can point to underlying issues, but you can catch them early on with this device to detect them early on and save you money in the long run, as well as extend the longevity of your truck's life.
EV2 gauges are easy to install and extremely durable, made with a front-seal construction and UV-stable outer shells, an LED backlight, and high accuracy on readings. Installation outside the cab is recommended and included is the R7110-10 tubing, but if you're not installing outside the cab, use the isolator part R7797 for a safe setup, which keeps fuel out of your truck's cab.
