ISSPRO
EV2 0-30,000 PSI Fuel Rail Pressure Gauge

2007.5+ 6.7L Dodge Cummins
2006-2009 6.6L GM Duramax (LBZ and LMM)

Many fueling boxes raise the rail pressure to increase horsepower, but can also cause damage to your expensive CP3 injection pump.  On the other hand, larger injectors, and modified CP3's can also cause too little pressure to be built into the rail, causing damage again.  Drive and race with confidence knowing that your fuel rail is not being starved or overfed with this fuel rail pressure gauge from Isspro.  EV2 gauges are driven with precision stepper motor movements and illuminated with LED lighting. This gauge is fully electric and features a 270 degree sweep. 

Each gauge is shipped with a complete wiring harness for installation. 

This gauge is offered in both:

• white face / black bezel / red pointer / turquoise backlighting
• black face / black bezel / red pointer / green backlighting.

Simply choose which style you prefer from below.
