RCD Performance CPX Fuel Injection Pump | 2011-2023 Powerstroke 6.7L

The RCD CPX Pump is a patented, high-output replacement for standard CP4 pumps, designed to increase reliability, prevent failures, and improve fuel system performance. It is engineered for hot-tuned engines and high-demand applications where stock pumps are prone to internal wear or lifter rotation issues.

Patented CPX Design

• Pinned lifter buckets prevent rotation and failure, even under extreme conditions
• New feed port prevents debris from entering plungers and barrels
• Direct drop-in replacement with no additional fuel lines or modifications required
• 24-month no-questions-asked replacement warranty

Variations Available

• Standard output upgrade (15-19 pump displacement, 7.5mm)
• 10% over output for tuned engines (8.25mm)
• High-output version (10.3mm, 38% over stock)

Why CPX is Better

The CPX maintains the OEM pump design with multiple plungers per revolution, ensuring precise nozzle pressure and consistent fuel delivery. It eliminates common issues found in other aftermarket eccentric pumps that skip firing events, which can cause engine damage.

Durability & Disaster Prevention

The CPX pump is CNC-machined internally to return fuel to the tank, preventing debris from entering injectors and fuel rails in case of internal failure. Common problems like lifter rotation or cam wear are mitigated, making additional “disaster kits” unnecessary.

Benefits

• Increased fuel displacement for high-demand applications
• Eliminates lifter rotation and internal pump failure
• Protects fuel injectors and rails from debris
• Direct OEM-style fitment
• Easy installation—no extra modifications needed
