  • This product may not work with the EGR cooler installed. It may need to be removed.
  • This product MUST be used in conjunction with custom tuning calibrations. Failure to install the correct calibrations can result in engine damage.
  • An aftermarket low pressure fuel system is recommended. AirDog and FASS are the two most commonly used.
  • This kit will replace the factory CP4 high pressure fuel pump with a CP3 high pressure fuel pump. CP3 pumps are commonly found on the older Duramax (and Cummins) platforms and have proven to be very reliable. This kit is also great because it allows the use of highly modified CP3 pumps that can be used to provide a SERIOUS amount of high pressure fuel flow.

    This kit includes a new stock CP3 pump.
