Product Description
Feed big power the right way. The INDUSTRIAL INJECTION 23D402 Dual CP3 Kit adds a second high-pressure CP3 to your 2007.5-2018 6.7L Cummins so rail pressure stays rock-steady under heavy load and high RPM. This version includes a CP3 pump with all the brackets, belt drive, lines, and hardware for a clean, OE-style install.
Fitment

Helpful Notes
- Lift pump recommended. A quality low-pressure supply is critical for CP3 longevity and pressure stability.
- '13-'18 trucks may require/benefit from a dual-CP3 controller harness depending on ECU strategy and pump combo (see “Dual CP3 Harnesses/Accessories).
- Professional installation and verification of rail pressure targets is strongly advised for high-power builds.
FAQ
Does this kit include a CP3 pump?Yes-23D402 is the with-pump kit. If you already have a secondary pump, see the no-pump kit (23D401) linked above.
Is tuning required after installing dual CP3s?Most performance builds will require tuning to command proper rail pressure and fueling. Work with a tuner who understands dual-pump strategies on the 6.7L Cummins.
Will this work with stock injectors and turbo?Yes-dual CP3s improve pressure stability even on stock injectors/turbo, and provide headroom for future upgrades.
What other parts should I add?A quality lift pump, ARP head studs, and fresh filtration are common adds. See the Recommended CPP Parts section above.
