Saving time and effort during the install of gauges is critical so you can get back on the road ASAP. GlowShift gauge accessories were made with this in mind for all different types of gauge installations.

For our fuel rail pressure gauges, we have a Fuel Rail Pressure Harness that enables you to connect the gauge directly to the fuel rail pressure sensor. All you have to do is disconnect the rail pressure harness connector, and plug the rail pressure pigtail harness into the factory sensor and sensor harness.

The main benefit of this pigtail harness is that you’re looking at a clean installation where you don’t have to splice into any factory wiring. On top of it you’re saving a whole lot of time on modifications that would keep you in the garage longer and on the road less.

This fuel rail pressure harness adapter is 6” long with 9” sensor and ground lead wires. Connect the green and black wires from the gauge harness to the matching wires on the pigtail harness and you’re ready to go.

Like our fuel rail pressure gauges, this fuel rail sensor harness is only compatible with the 2003-2018 Dodge Ram 5.9 or 6.7 Cummins, and 2002-2018 Chevy Silverado or GMC Sierra 6.6 Duramax.

Use it to easily install one of our fuel rail pressure gauges and you’ll have access to incredibly accurate diesel truck rail pressure readings from 0 to 30,000 PSI in no time.
