Fleece Performance 03-07 Dodge 5.9L Cummins CP3K

When you're working on your 2003-2007 Dodge Ram 2500 with the 5.9L Cummins engine, you might notice a drop in fuel flow and rail pressure once you get past 3,000 RPM. That's often the factory CP3 injection pump hitting its limit. The Fleece Performance CP3K is a modified version of that stock pump, specifically built to get rid of that restriction and keep fuel flowing strong even at higher RPMs.

Fleece Performance takes each CP3 pump and puts it through rigorous testing on their in-house engine simulator and pump test stand. This ensures that every pump they send out is ready to perform under real-world driving conditions. By modifying the internal flow path, this pump helps maintain consistent fuel delivery, which can translate to more reliable power when you need it, especially if you've made other upgrades to your engine.

This is a direct replacement for your factory CP3 pump, designed to fit right into your 2003-2007 Ram 2500 or 3500. Keep in mind that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper setup and any additional components you might need.
