CPX Fuel Injection Pump for 2011+ 6.7L Powerstroke Ford Super Duty
The CP4 Pump Reengineered for Reliability
CPX fuel injection pump for 6.7L Powerstroke fixes the common failure points found in the factory CP4 design. As a result, it improves reliability while maintaining consistent fuel delivery under load.
The factory CP4 pump is known to fail and contaminate the entire fuel system. This upgrade addresses that issue with internal improvements designed to prevent those failures.
Engineered Internal Upgrades
The CPX pump features pinned lifter buckets that prevent rotation, which is the primary cause of internal failure. Because of this, it reduces metal-on-metal contact and helps protect critical components.
In addition, a redesigned feed port prevents contaminated debris from entering the plungers and barrels, acting as a built-in disaster prevention system. :contentReference[oaicite:1]{index=1}
