Description: This CP3 conversion kit is designed for 2011 - 2016 GM vehicles with the LML 6.6L Duramax engine.

With our kit, you can easily adapt a CP3 to your 2011 - 2016 Duramax. Paired with piezoelectric injectors, a CP3K conversion can support over 600 RWHP, and a PowerFlo 750 conversion can handle nearly 850+ RWHP. Fleece Product Number: FPE - LML - CP3 - NP. Features include a high - pressure fuel rail line, fuel rail plug and nut, CP3 block adapter with O - ring, and more. Installation comes with an LML CP3 Conversion Fuel Pressure Regulator Table. Warning: Incorrect use may violate local, state, and federal laws related to emissions, traffic, registration, and safety. It may damage vehicle components, void the factory warranty, and require special driving skills. This product may not work with the EGR cooler installed and must be used with custom tuning calibrations to avoid engine damage.
