Fleece CP3 Conversion Hardware Kit (No Pump) for 2011-2016 Chevy/GMC LML Duramax
FPEFPE-LML-CP3-NPAlready have a CP3 for your LML and just need everything else to convert? This is the hardware kit without the pump.
Since its introduction, the CP4 has proven to be less reliable and less capable than the CP3 used on earlier Duramax platforms. When a CP4 fails, it's extremely costly and requires replacement of the entire fuel system. Converting your 2011-2016 LML from the CP4 to a CP3 improves reliability and fueling capability, and helps you avoid that failure down the road.
This kit gives you OEM quality components: Fleece exclusive molded hoses for the fuel feed and return, high flow CP3 fuel fittings, and Fleece's valley feed line to support aftermarket lift pump and filter applications. It does not include a CP3 injection pump.
