High Performance Fuel Rail Plugs for the Cummins and Duramax Diesel Engines

The installation of a Fuel Rail Plug will replace your OEM fuel release valve without having to shim it with washers.

Aftermarket performance tuners often require increased fuel rail pressures that cause the fuel rail release valve to open. The appearance of trouble codes P00087 and P1011 are a sign of the OEM fuel rail pressure release valve has opened. The installation of a Fuel Rail Plug will eliminate the valve which allows the required fuel pressure to be maintained to the rail and injectors. The installation of a Fuel Rail Plug prevents the power level drop and the associated trouble codes from appearing with a check engine light warning.

This Fuel Rail | Pressure Relief Valve (PRV) Plug is currently available for the following Turbo diesel engines:

• 2003 to 2007 Dodge Ram 5.9L Cummins
• 2007.5 to 2019 Dodge Ram 6.7L Cummins
• 2004.5 to 2016 GM 6.6L Duramax LLY, LBZ LMM, LML diesel

The installation of a Fuel Rail Plug offers several benefits:

• Rail Plug replaces the factory pressure relief valve located on the fuel rail.
• Insures rail pressure drops during full-throttle driving
• Race Plug prevents any chance of rail pressure drop.
• Prevents lost rail pressure which equals a loss in horsepower, torque, and mileage.
• Installation increases of up to 2,000 psi obtained in the fuel rail.
• It can be used as a diagnostic tool to determine if the pressure relief valve has failed.
• A Race Plug seals in up to 30,000 psi of rail pressure
• Improves engine starting
• The Race Plug is a must-have for the high performance Cummins or Duramax diesel.
• Higher rail pressure ensures the improved atomization of diesel fuel for increased combustion efficiency
• Increased engine efficiency equals more MPG, HP, and Torque.
• You cannot make more power without more fuel!

What are the benefits of installing a Fuel Rail Plug in my 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. 

The main benefit of Diesel Fuel today's Ultra Low Sulfur Diesel Fuel.

• The lower volatility level of diesel fuel when compared to gasoline results in lower emissions of both carbon monoxide and hydrocarbons. 
• Another huge benefit is the safety provided by today's diesel fuel Safety. Diesel Fuels Lower-volatility levels means the fuel is more stable. The lower volatility of diesel compared to gasoline makes it a safer and more stable fuel to handle.

The problem with diesel fuel is that it does not easily become a vapor. This is one of the main reasons why the installation of a fuel rail plug can increase engine efficiency in your diesel engine.

For diesel fuel to mix well with the incoming air charge the following items are required: 

• Improvement in Diesel Fuel Atomisation
• Increase in the Dispersion rate of diesel fuel.
• Improved level of diesel fuel Vapourisation with increased rail pressures
• Increased Penetration of the smaller sized particles into the cylinder.

The installation of a Fuel Rail Plug combined with improved Engine Tuning provides dramatic improvements in all four of these characters.

The increased fuel rail pressure provided by the Fuel Rail Plug provides the following benefits in your Diesel Engine:

• Reduced Emission Levels
• Increased Horsepower Level.
• Increased Torque Output Level.
• Improved Combustion efficiency.

What Is Diesel Fuel Volatility?

The Volatility level refers to how easily the diesel fuel will vaporize. It affects how easily you can start your engine, warm it up, and how well it runs. Diesel fuel comes in two basic grades one known as On-Road or #2 Diesel and the other is Off-Road diesel fuel each with different volatility levels. Automobiles and large trucks run the 2-D grade Ultra-Low Sulfur diesel fuel. The lower volatility of diesel compared to gasoline results in emissions lower in carbon monoxide and hydrocarbons, although cold weather makes diesel engines more difficult to start.

What Is The Diesel Fuel Flash Point?

Flashpoint refers to the lowest temperature at which a fuel will vaporize and ignite. The Flashpoint and Volatility very inversely. The lower the flashpoint, the higher the volatility and the increased power output created by diesel fuel.

Gasoline has a higher volatility than diesel so it contains lower power levels.
