ATS Diesel Fuel Rail Pressure Plug for 2007.5–2012 Dodge Ram 6.7L Cummins
The ATS Diesel Fuel Rail Pressure Plug replaces the factory pressure relief valve on 2007.5–2012 Dodge Ram 2500, 3500, 4500, and 5500 trucks equipped with the 6.7L Cummins diesel engine.
This plug blocks fuel bleed-off from the rail, allowing the fuel system to maintain higher rail pressures (over 5000 PSI) required for larger injectors and performance tuning. It provides consistent fuel delivery, sharper throttle response, and improved reliability under high-load conditions.
