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. If your Cummins 5.9L engine is one that has been modified and is running a tuner that is 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. if your Cummins engine is now running modified injectors this fuel rail for the common rail will help ensure adequate fuel flow to your high-performance fuel 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.

5.9L Cummins Diesel Common Rail Fuel Plug Features:

  • Constructed on a CNC machine for the highest precision machining possible.

  • FAQWhat are the benefits of installing a Fuel Rail Plug in my 2003 to 2009 5.9L Cummins Diesel Engine? The installation of a Fuel Rail Plug or Race Plug allows your CP3 Fuel Injection Pump to maintain higher fuel pressures in the fuel rail. The higher the fuel injection pressure, the better the atomization of the diesel fuel being injected into the cylinder. Improved atomization of the fuel diesel leads to an improvement in the air-fuel mixture and increased combustion performance. With the improved combustion of the air-fuel mixture comes better engine performance, higher power levels, and reduced emissions.
