Cummins 2003 to 2007 Dodge Ram 5.9L Common Rail Diesel Fuel Rail Plug

The Dodge Ram 5.9L Common Rail Cummins diesel engine contains a relief valve in the fuel rail, This fuel pump relief valve is designed to relieve the fuel rail pressure at approximately 25,000 PSA. The common rail uses the relief valve to avoid damage to the fuel injectors.  Cummins 5.9L engines that have been modified and are running a tuner are designed to deliver fuel rail pressure greater than 25,000 PSI. The increased level of fuel pressure then causes the OEM relief valve to open which then limits the fuel supply to the injectors. Installation of this Cummins 2003 to 2007 Dodge Ram 5.9L Common Rail Diesel Fuel Rail Plug maintains fuel pressure and maximum engine performance.
