    Convert your 2011-2016 Duramax's fuel system from a CP4 to a CP3 high-pressure pump and get performance and peace-of-mind. Since its introduction, the CP4 has proven to be less reliable and less capable than the CP3 used in previous Duramax platforms. Fleece's newest kit includes all of the hardware necessary to replace the troublesome CP4 with a CP3 and requires no tuning changes and maintains all factory emissions controls.

    QUESTIONS & ANSWERS

    Ask a Question

    • Hi I had a question about a LML Cp3 conversion if the fuel system is still good can I just spend $3-4k to convert it now or do I have to wait for it to blow up and then spend the 7-10k?

      You could definitely be proactive and do the conversion right away. However, if you decide to stay with the CP4, we recommend that you consider installing a Fuel System Saver.
