EXERGY E04 10105 SPORTSMAN CP3 PUMP (LBZ BASED W/FCA) 2001-2004 GM DURAMAX 6.6L LB7

The EXERGY E04 10105 SPORTSMAN CP3 PUMP is the ultimate solution for those experiencing a loss of rail pressure due to a worn-out CP3 pump in their 2001-2004 GM Duramax 6.6L LB7 engine. Whether you're seeking a factory replacement CP3 pump or have tried unsuccessfully with "parts kit" alternatives, our Sportsman CP3 pump offers unmatched quality and affordability.

This upgraded pump is designed to deliver reliable performance for power levels ranging from stock to 650+HP without the need for extensive modifications or tuning. The Exergy Sportsman pumps boast multiple enhancements over stock pumps, including higher flowing valves for increased longevity, DLC coated plungers to reduce scoring/seizing risks, and more surface area to withstand pumping loads effectively. Unlike stock pumps that plateau in flow beyond 3,000 RPM, our pumps continue to increase flow with RPM.

The development of our Sportsman CP3 pump involved rigorous research and testing to ensure durability and performance. Each pump undergoes meticulous testing to guarantee proper function in real-world conditions, up to 4500 RPM and 29,000 psi. Third-party verification confirms compliance with Federal Emission requirements, providing customers with peace of mind.

Compatible with LB7 engines, the LBZ-based pump with an LB7 fuel pressure regulator streamlines tuning processes. While a lift pump isn't mandatory, optimal pump performance is achievable with a fuel supply of 150 GPH at 8-10 psi. Notably, there is NO CORE CHARGE or CORE RETURN NEEDED with our Sportsman CP3 pump.

From 2001 to 2004, this Exergy Performance pump fits models such as Chevrolet Silverado 2500 HD, Chevrolet Silverado 3500, GMC Sierra 2500 HD, and GMC Sierra 3500, in 6.6L engines. Trust Exergy to deliver top-quality fuel system components for your vehicle.
