Description

Fits 6.6L Duramax, 6.7L Cummins, 6.7L Powerstroke, Custom Applications

The S&S Diesel Motorsport Ordnance 650 CP3 is a purpose-built, max-effort competition pump designed for extreme performance and high-RPM stability. Starting as a brand-new Bosch CP3, each unit is heavily modified and finished in a durable Cerakote to prevent corrosion. The Ordnance 650 features a patent-pending billet aluminum flange with an integrated gForce Block, eliminating fuel disruption during hard launches and simplifying the overall system design.

Engineered to support 1,200+ HP, this pump delivers a massive 1,850 mm3/rev displacement and is tested up to 8,000 RPM. Whether you are sled pulling or drag racing, the Ordnance 650 provides the most consistent high-pressure fueling on the market.

*IMPORTANT* Please read the “Additional Information” section.

Additional Information

• Tuning: Custom tuning is mandatory. This pump does not follow a stock curve. Refer to the included data sheet for IMV curve data (2,200 mA required to completely close the IMV).
• Plumbing: Use a -6AN hose for the low-pressure feed and a dedicated -6AN return line to the fuel cell.
• Supply Pressure: The use of an S&S Regulated Filter Head (FDS-RFH-ASM) is highly recommended to maintain the required 140 PSI supply pressure.
• Fitment: LML Duramax, 2019+ RAM, and Ford 6.7L models require a CP3 Conversion Kit for installation.
