Product Description
S&S Diesel CP3-CU-14-HS-SP – Cummins 14mm High Speed CP3 w/ SP3000 (New, 6.7L-Based)
Put race-ready fuel on tap with S&S Diesel’s 14mm High Speed CP3 (1,850 mm³/rev) paired with the SP3000 mechanical supply pump (flows up to 3,000 L/hr). This new, 6.7L-based CP3 is engineered to sustain delivery well beyond high RPM where conventional pumps nose over—ideal for serious 5.9L and 6.7L Cummins builds.
- High output: 1,850 mm³/rev “High Speed” geometry sustains delivery at elevated RPM.
- Integrated supply: SP3000 mechanical pump replaces the small OE lift/supply pump and supports extreme demand.
- New unit: Built from new components (no core).
- 6.7L-based CP3: Direct for 2007.5–2018 6.7L; simple line adaptation for 2003–2007 5.9L.
Fitment
2003–2018 Dodge Ram 2500/3500 Cummins 5.9L/6.7L 24-valve common-rail
- Direct fit for 2007.5–2018 6.7L Cummins (CP3-based systems).
- For 2003–2007 5.9L Cummins, use a high-pressure line adaptation kit when installing a 6.7L-based CP3: Fleece HP Fuel Line Adaptation Kit – 5.9L to 6.7L CP3.

FAQ
What makes this a “High Speed” CP3?Internal geometry and control optimizations maintain effective displacement and volumetric efficiency at elevated RPM compared to standard strokers.
Do I need an external electric lift pump with the SP3000?
The SP3000 is a mechanical supply pump designed to replace the small OE supply pump and provide up to 3,000 L/hr at pressure. In many competition builds it eliminates the need for an additional electric lift pump when the system is plumbed correctly.
Will this bolt onto a 2003–2007 5.9L?
Yes—with the proper high-pressure line adaptation for installing a 6.7L-based CP3 on a 5.9L. See the recommended Fleece adaptation kit above.
Is a core charge required?
No. This is a new pump package; no core is required.
