FAQ
Will this 6.7L-based 14mm CP3 bolt onto my 5.9L (2003–2007)?Yes—mechanically it mounts, but you must use a 5.9L→6.7L CP3 high-pressure fuel line adaptation kit. We recommend the Fleece kit linked above.
Do I need an upgraded lift pump with this CP3?
Strongly recommended for consistent supply under load. See our lift pump category links above for 03–07 and 07.5–18 applications.
Is this pump new or remanufactured?
It is a new S&S Diesel pump built from a 6.7L-based core.
What power level is this suitable for?
14mm high-speed CP3s are commonly used in serious street/strip and competition builds where higher RPM fueling is required. Ensure your injectors, tuning, and supply system are matched.
Does it include the SP3000 mechanical supply pump?
No. This listing is for the 14mm High Speed CP3 only. If you need an integrated mechanical supply solution, see S&S kits that include the SP3000 (contact us).
