Description

S&S Diesel Motorsport's CP3 conversion kit for LML Duramax engines replaces the failure-prone CP4.2 high-pressure pump with a more reliable CP3 pump. CP4 pump failures often damage the entire high-pressure fuel system. This specific kit (MPN: LML-CP3-WO-PUMP) is supplied without the CP3 pump, is intended for competition use, and requires tuning.
