S&S Diesel CP4 to DCR Fuel Pump Conversion Kit - Ford 6.7L Power Stroke (2011-2024)

The CP4 pump on Ford 6.7L Power Stroke trucks has a well-earned reputation for failing without warning, sending metal debris through the fuel system and leaving owners facing repair bills that can exceed $10,000. The S&S Diesel CP4 to DCR Fuel Pump Conversion Kit removes that risk entirely by replacing the CP4 with a durable, plug-and-play DCR pump — no cutting, no bypass, just a direct swap.

Built on a proven Stanadyne DCR pump platform, S&S and PurePower engineers developed a version specifically matched to the 6.7L Power Stroke's output curve, so no ECU recalibration is needed. The two-piston design runs with low hydraulic and acoustic noise, fast response, and is compatible with biofuel and low-lubricity fuel. It delivers up to 1,250 mm3 of fuel per revolution — 25% more than a CP4.2 — giving plenty of headroom even for injectors with high return.

• OE fit and function; true drop-in replacement
• No ECU calibration required
• Corrosion-resistant Fuel Control Actuator (FCA)
• Pressure-lubricated cam and bushings for durability
• Biofuel and low-lubricity fuel compatible
• CARB legal (EO# D-756-7)
• 2-Year / Unlimited Mile manufacturer warranty
• Can help owners avoid $10,000-$15,000 in fuel system repair costs

Note: this kit is not compatible with a previously installed CP4 Disaster Prevention/bypass kit — that must be removed first, since the metering valve differs. 2011-2016 model years also require a one-time-use vacuum pump gasket, not included.

Fits: 2011-2023 Ford F-250/F-350/F-450/F-550/F-650/F-750 with 6.7L Power Stroke
