2003-2007 DODGE 5.9L CUMMINS

The H&S Motorsports 451003 Dual High Pressure Fuel Kit has been specially designed to maximize performance in your 2003-2007 Dodge 5.9L Cummins. The Cummins engine is known for its strength and reliability and H&S Motorsports did their best to apply the same characteristics in the development of this product.

Unlike most dual pump kits on the market, the H&S Motorsports kit features a TRUE dual rail feed solution. With this system, the secondary CP3 pump feeds the back of the fuel rail independently to ensure that the high pressure fuel lines do not become a restriction at any engine RPM or power level. This also allows the factory CP3 pump and high pressure line to remain in the stock configuration. The unique pump mounting system positions the secondary CP3 pump low and the serpentine belt is routed in such a way that it maintains optimal surface contact for the secondary CP3 pump and the factory power steering pump.

Even with the standard "stock" pump, this system is easily capable of 800+ WHP worth of high pressure fuel supply! If that's not enough for you H&S Motorsports also offers modified 5.9L and 6.7L Cummins CP3 pumps to meet your fueling demands. The included CP3 pump is a brand new OEM unit. That's right, BRAND NEW, not a remanufactured unit like many shops include. The key to ensuring the longevity of any high pressure fuel pump is by providing the high pressure fuel system with clean, waterless diesel fuel. Any fuel contamination that reaches the high pressure fuel system can be detrimental to reliability and performance. H&S Motorsports recommends using an AirDog, FASS or similar lift pump for proper filtration and water-separation.

If you are looking for the ultimate in high pressure fuel supply, look no further than the H&S Motorsports Dual High Pressure Fuel system.
