6.7L Ford Powerstroke CP4 Bypass Kit

6.7L Ford Powerstroke Disaster Prevention Kit CP4 Conversion Kit

The Smeding Diesel CP4 bypass kit reroutes the fuel that runs through the inside of the CP4 back toward the tank instead of letting it feed the high pressure side. If the pump starts to come apart, the metal it sheds has a way out instead of being pushed into your rails and injectors.
