This new and improved CP4.2 from SPE is the perfect upgrade for your 6.7L Powerstroke. This upgraded high pressure fuel pump is capable of supporting 600-650hp. This pump includes the Exergy Performance MPROP/FCA upgrade.
The factory MPROP/FCA (fuel control actuator) has a course single layer screen that will allow metal debris past it in the case of a pump failure and will typically take out the entire fuels system when it does fail. This patent-pending MPROP from designed by Exergy Performance has a two layer 25 micron screen that will prevent metal debris larger than 25 micron from entering the rest of the fuel system, most commonly causing pump failure. With this upgraded pump, the truck will shut off before a whole system failure would occur. These MPROP's will not affect the output of the pumps unless an issue arises causing debris to build up.
*We recommend using this in conjunction with the factory lift pump.
