The Fleece LML CP3 Conversion Kit FPE-LML-CP3-NP (Without Pump) is a customizable way to convert the fuel system in your 2011-2016 GM 6.6L Duramax LML from a CP4 to a CP3. Your LML Duramax's durability and fueling capability will be improved with a CP3 upgrade. Since its release, the CP4 has proven to be less reliable and capable than the CP3 used in previous Duramax fuel systems. Failures of the CP4 are incredibly costly and need the replacement of the entire fuel system. This kit is a no-tuning-required solution for the LML Duramax platform so you can convert your CP4 to a CP3 and save money down the road. This kit includes high-flow CP3 fuel connectors, Fleece’s unique molded fuel feed and return hoses, and our valley feed line to enable aftermarket lift pump and filter installations.
