The upgraded Fleece Performance PowerFlo 1000 CP3 is proven to support 1000 rwhp with proper complimenting modifications. This upgrade also eliminates the factory fuel flow restriction at 3000 rpm. Stock CP3 pumps can be the cause of fuel flow loss and rail pressure decrease after 3000 rpm which correlates to lost horsepower. Maintain desired fuel rail pressure throughout your entire rpm range while always providing enough fuel. Every Fleece Performance CP3 is tested on their in-house engine simulator to stimulate real world situations to ensure each pump is ready to work for you.


  • Full fuel delivery to 6,000+ RPM.
  • New OEM unmodified FCA
  • New Bosch CP3 - no core charge or core to return
  • Fleece Performance high flow feed and return fittings
  • A 6.7L Cummins based CP3 is provided in this kit along with a high pressure line to adapt to the 5.9L engine - see installation instructions for application details.
