Fleece Performance FPE-LML-CP3-NP CP3 Conversion Hardware Kit No Pump 2011-2016 LML Duramax

Upgrade your 2011-2016 LML Duramax's fuel system reliability with the Fleece Performance CP3 Conversion Hardware Kit. This comprehensive kit allows you to convert from the problematic CP4 injection pump to the proven CP3 design, significantly improving both reliability and fueling capability.

The CP4 injection pump has a well-documented history of catastrophic failures that contaminate the entire fuel system, resulting in repair bills exceeding $10,000. By converting to a CP3 pump, you eliminate this risk while gaining superior fueling capacity for modified engines. This kit includes everything needed for the conversion except the CP3 pump itself, allowing you to source your own pump or reuse an existing unit.

• High-flow CP3 feed and return fittings for optimal fuel delivery
