Fleece CP3 Conversion Kit with CP3 for 2011-2016 LML Duramax

Convert the fuel system of your LML Duramax from a CP4 to a CP3 to enhance reliability and fueling capability. Since its introduction, the CP4 has demonstrated lower reliability and performance compared to the CP3 used in previous Duramax platforms. Failures of the CP4 can be extremely costly, often requiring a full replacement of the entire fuel system. To avoid such expensive issues in the future, consider our complete CP3 conversion kit designed for the 2011-2016 LML Duramax platform, which requires no tuning.
