This customizable conversion kit without the pump is a no tuning required solution for your diesel pickup. The upgraded Fleece Performance CP3 eliminates the factory fuel flow restriction at 3000 rpm. Stock CP3 pumps can be the cause of fuel flow loss and rail pressure decrease after 3000 rpm which correlates to lost horsepower. Maintain desired fuel rail pressure throughout your entire rpm range while always providing enough fuel. Every Fleece Performance CP3 is tested on their in-house engine simulator to stimulate real world situations to ensure each pump is ready to work for you.
