Since its introduction, the CP4 has proven to be less reliable and less capable than the CP3 used in previous Duramax platforms. Failures of the CP4 are extremely costly and require replacement of the entire fuel system. Our kit provides you with OEM fit-and-finish features like a brand new Bosch CP3 with heavy duty 10mm cam, Fleece exclusive molded hoses for the fuel feed and return, high flow CP3 fuel fittings, and our valley feed line to support aftermarket lift pump applications. Features: Heavy Duty CP3 with 10mm displacement cam High flow CP3 feed and return fittings Preformed feed and return fuel lines Kit Contents: CP3 to rail high pressure fuel line High flow CP3 feed and return fuel fittings Preformed feed and return fuel lines CP3 mounting adapter Dosing injector fuel lines and mounting bracket FCA extension harness Low pressure fuel feed lines Hardware kit Application Notes: This kit has been tested for use in stock application trucks that did not utilize a fuel lift pump. For optimal performance, if the truck is equipped with a lift pump, the feed pressure to the CP3 should not exceed 2 psi. Engine surging may be induced by the additional fuel pressure of a lift pump operating at pressures over 2 psi. For higher lift pump pressures, FCA table values will require adjustment.

This comprehensive kit replaces the less reliable CP4 fuel pump with a brand new Bosch CP3 featuring a robust 10mm displacement cam, ensuring consistent fuel delivery and improved engine performance. The kit includes high flow CP3 feed and return fittings, preformed fuel lines for easy installation, and a valley feed line designed to support aftermarket lift pump applications. These OEM fit-and-finish components are engineered for durability and optimal operation in your 2011-2016 GM 2500 or 3500 Duramax diesel truck, providing a significant upgrade over factory systems. The installation involves replacing the original fuel pump and associated lines, resulting in a more reliable fueling system that reduces the risk of costly failures and downtime. Properly installed, this kit enhances fueling efficiency and engine responsiveness, especially in high-demand driving conditions. It has been tested for stock applications without a fuel lift pump, but adjustments may be necessary if a lift pump is present, as excessive feed pressure can induce engine surging. This product is covered under SC-E emissions certification and is designed to meet the highest standards of quality and performance. Whether you're looking to improve your truck's dependability or prepare for increased power modifications, this Fleece Performance CP3 conversion kit is an essential upgrade for your Duramax LML diesel engine.
