Product Description

The Exergy E04 10105 Sportsman CP3 Fuel Pump is a high-performance replacement designed for2001-2004 GM Duramax LB7 diesel engines. Built from a brand-new LBZ-based CP3 platform andequipped with the correct LB7 fuel control actuator, this pump delivers increased durabilityand improved fuel flow compared to the original factory unit. It serves as a direct-fitreplacement while offering enhanced performance for both stock and lightly modified dieselapplications.

Internally upgraded with higher flowing valves and DLC-coated plungers, the Sportsman CP3is engineered to provide consistent rail pressure and reliable fueling even at elevatedengine speeds. Unlike many factory pumps that plateau around 3,000 RPM, this pump continuesto increase fuel flow up to approximately 4,500 RPM, making it an excellent option fordaily-driven trucks, towing setups, and builds targeting up to roughly 650 horsepower.Each pump is individually tested across its full operating range to ensure proper pressure,flow, and reliability before installation.

Designed as a bolt-on upgrade, the Exergy Sportsman CP3 installs using factory mountingpoints and fuel lines for straightforward replacement of worn or failing pumps. While itcan operate with the stock fuel supply system, pairing it with a quality lift pump isrecommended to maintain stable fuel pressure and maximize overall fuel system performance.
