Understanding the CP4 Pump Issue

The CP4 high-pressure fuel pump, standard in 2011 to current Ford Super Duty diesel trucks, has been known to fail without warning. Such failures can cause sudden power loss and extensive damage to the high-pressure fuel system, with repair costs often exceeding $10,000. These issues have led to recalls and lawsuits against various auto manufacturers utilizing the CP4 in their vehicles.

The DCR Pump Conversion: A Reliable Alternative

S&S Diesel Motorsport, in collaboration with PurePower Technologies, has developed the Durable Compact Rotary (DCR) pump as a direct replacement for the problematic CP4. This plug-and-play solution offers original equipment (OE) fit and function without the need for additional ECU calibration.
