Installing a fuel pressure gauge in your diesel truck empowers you to monitor your fuel system and protect your engine, ultimately increasing your truck's longevity. It provides real-time visibility into the fuel system, allowing you to monitor the pressure level while driving. Fuel pressure fluctuations can indicate underlying issues in the fuel system. You can quickly identify irregularities or drops in pressure, helping you diagnose potential problems such as clogged filters, failing pumps, or leaks. Early detection allows for timely maintenance and prevents costly repairs down the line.
To make installation easy on Dodge Ram 5.9L Cummins, select the checkbox for the Tapped Banjo Bolt. This specially designed bolt has a bigger hex that is drilled to accept 1/8 NPT male thread. On 1998.5-2002 Dodge trucks equipped with the Bosch VP44 injection pump, this bolt replaces the banjo bolt on the fuel supply line making installation a breeze.
When installing a mechanical fuel pressure gauge, it's best if you don't route high-pressure fuel into the inside of your truck. Instead, be sure to select the checkbox for the Fuel Pressure Gauge Isolator kit to avoid this potential disaster. The diesel fuel pressure gauge isolator ensures fuel can not enter the cab even if the tubing or gauge fails. For a complete kit, also add the braided stainless steel hose kit to route to your isolator.
Some Ford trucks from 1999-2007 will not be compatible with this 8-volt gauge. Please see the PRODUCT DOCUMENTS for how to check the voltage on your Ford. If this 8-volt gauge is not compatible, then you will need the 1.7-volt gauge instead.
