This kit is designed to work with factory OE trucks without tuning and modifications.

  • No Tuning Needed
    Our CP3 Conversion Kit is a direct replacement for the factory CP4 and will not cause check engine lights. No need to spend extra money on custom tuning or programmers, our kit works with the factory tuning.
  • Emissions Compliant
    Our CP3 Conversion Kit has been designed to be used with all of the factory emissions equipment. Your truck will run as if it was from the factory.
  • Proven Reliability
    The CP3 fuel pump is proven to have longevity and to be reliable in performance applications.
  • Remove the Worries
    The CP4 has known failure issues that cannot be remedied. These issues, if they occur, can cause damage to other major fuel system components.
  • 10mm Stroker Shaft
    To help increase rail pressure when fueling to higher rpms we have designed these pumps with our industry leading 10mm stroker shaft.

Reviews

  • how long does installing time call for?

    Cody Derobbio | 10/8/2021

    4-6 hours. Here is the installation manual.

  • Will this supply sufficient fuel for a tuned ho with a 5 position switch? Max setting is around 180 hp over stock.

    Gary Zemke | 8/18/2020

    Yes, as long as you have an upgraded lift pump.
