The Fleece LML CP3 Conversion Kit FPE-LML-CP3-WP from XDP is a safe and easy way to convert the fuel system from a CP4 to a CP3 in your 2011-2016 GM 6.6L Duramax LML. With a CP3 conversion, you will improve the reliability and fueling capability of your diesel-powered Chevy Silverado/GMC Sierra HD. The CP4 has proven to be less dependable and capable than the CP3 utilized in prior Duramax platforms since its introduction. CP4 failures are extraordinarily expensive and necessitate the replacement of the complete fuel system. Convert your CP4 to a CP3 and save money down the road with our complete, no-tuning-required solution for the 2011-2016 LML Duramax platform. This kit includes OEM-quality components such as a brand new OEM CP3, Fleece unique molded fuel feed and return hoses, high-flow CP3 fuel connectors, and a valley feed line to enable aftermarket lift pump and filter installations.
