Industrial Injection 237402 Dual CP3 Fuel Injection Kit 2003-2007 Cummins 5.9L

The Industrial Injection 237402 Dual CP3 Kit is a high-performance fuel system upgrade designed for the 2003–2007 Dodge Ram equipped with the 5.9L Cummins diesel engine. This kit adds a second CP3 high-pressure fuel pump alongside the factory unit, dramatically increasing fuel volume and rail pressure capacity to support high-horsepower diesel builds.

A dual CP3 setup is one of the most popular fuel system upgrades for performance-oriented Cummins owners running larger injectors, aggressive tunes, or compound turbocharger systems. By running two pumps in parallel, the system ensures adequate fuel supply under hard acceleration and sustained high-load conditions where a single stock CP3 pump would otherwise become the bottleneck.

Key Features:

• Designed specifically for 2003–2007 Cummins 5.9L common rail diesel engines
• Includes second CP3 high-pressure injection pump and necessary hardware
• Increases fuel rail pressure capacity for high-demand performance applications
• Ideal for builds running upgraded injectors, compound turbos, or high-output tunes
• Bolt-on design engineered for straightforward installation
• Manufactured by Industrial Injection, a trusted name in diesel performance fuel systems

Industrial Injection is a Utah-based diesel performance company with decades of experience in fuel injection technology. Their dual CP3 kits are a proven solution for 5.9L Cummins builds requiring reliable high-volume fuel delivery beyond what the factory single-pump system can provide.
