CP4 to DCR Pump Conversion for 2011+ Ford 6.7 Power Stroke | S&S Diesel Motorsport

Overview

Ford 6.7L Power Stroke CP4 pumps have earned a reputation for unexpected failures that can cause sudden power loss and costly fuel system repairs. In worst cases, owners may confront towing and high replacement costs. This context is the backdrop for a direct, drop-in upgrade from S and S Diesel Motorsport in collaboration with PurePower, designed to restore confidence without altering engine tune.

Direct drop-in solution

The CP4 to DCR Pump Conversion uses a proven Stanadyne DCR design, tailored for the Ford 6.7L Power Stroke. It matches the CP4 output curve and does not require calibration changes, offering an OE-like fit and function. The kit combines OE-grade braided hose and steel fuel lines to deliver a clean, factory-like appearance and durability.

• More durable plug-and-play replacement for the CP4 with OE fit and function; no tuning required.
• Ford-specific variant of the Stanadyne two-piston DCR pump co-developed by S and S and PurePower.
• Biofuel and low-lubricity fuel compatible; patented eccentric-drive pumping technology; pressure-lubricated cam and bushings; corrosion-resistant VCV.
• Displacement of 1,250 mm3 per revolution, which is CP4.2 plus 25 percent, ensuring ample flow for aging injectors.
• Fits 2011 to 2025 Ford F250-F750 diesel trucks.
• Emissions compliant under EO number D-756-7 with CARB certification.

What this could mean for your truck

The DCR pump is designed to be compact, modular, and quieter under load, while delivering quick response times. It is compatible with biofuels and low-lubricity fuels, supporting a broader range of fueling options you might encounter on the road or at the shop.

• Potential for reduced risk of high-pressure fuel system failures and extended reliability on daily work trips.
• Plug-and-play installation that preserves OE appearance and is less disruptive to workflows.
• Robust construction with corrosion-resistant components and debris protection for longevity in harsh environments.
• Emission compliance ensures alignment with regulatory expectations in supported markets.

What to expect in real-world use

Owners may notice steadier cold starts, consistent engine responsiveness, and a smoother idle as the new DCR pump provides steady fuel delivery. While not a guarantee of performance improvements, this upgrade is designed to offer a dependable alternative to CP4 components that have shown vulnerabilities in the field.
