Dirty Hooker Diesel 06-10 GM 6.6L Duramax DHD Improved Rail Pressure Sensor Harness

This direct OE replacement jumper harness joins the fuel rail pressure sensor to the engine harness. These harnesses are subject to extreme heat and are often targets for rodents.

DHD's improved harness is designed to replace your flimsy OE jumper. DHD's jumper features a full foil sleeve, larger gauge primary wiring and fully sealed connector integrations. 

DHD always recommends replacing this complete harness section rather then doing wire repairs. High resistance repairs could lead to idle fluctuations, smoky engine performance and erratic engine rpm.
