What is the main benefit of the Fleece Performance CP3K pump compared to a stock pump?

The main benefit is that the CP3K pump is modified to remove the factory-imposed fuel flow restriction that occurs after 3,000 RPM. This allows for more consistent fuel delivery and rail pressure at higher engine speeds, which can result in improved engine performance.

How do I know this pump will work correctly?

Fleece Performance tests every CP3K pump on their in-house engine simulator and pump test stand. This ensures that each unit is ready to perform reliably in real-world driving conditions before it's shipped to you.

Does this pump come with all the necessary hardware for installation?

The manufacturer's description does not specify if installation hardware is included. It is recommended to refer to the manufacturer's installation instructions or contact Fleece Performance directly for details on what is included with the pump.

Product Details

Fleece Performance is known for making parts that help diesel trucks perform better, and this modified CP3 injection pump is a prime example. If you're driving a 2011-2018 Ram 2500 or 3500 with the 6.7L Cummins engine, you might notice a drop in fuel flow and rail pressure once you get past 3,000 RPM. That's because the factory CP3 pump has a built-in restriction that limits how much fuel it can push at higher engine speeds, leading to lost power.

This CP3K pump from Fleece Performance addresses that issue directly. They take a factory 6.7L Cummins CP3 and modify it to remove that specific restriction, allowing for more consistent fuel flow and rail pressure even when the engine is working hard. Each pump is tested on Fleece's own engine simulator and pump test stand to make sure it's ready to handle real-world driving conditions right out of the box. This means you can expect a well-built unit that's ready to help your truck perform at its best.

Upgrading your fuel system with this pump is a solid step toward unlocking more potential from your 6.7L Cummins. It's designed to be a direct replacement for your stock pump, making installation straightforward for those familiar with diesel fuel systems. You'll want to ensure you have the necessary tools and knowledge for a fuel system component replacement, or consider having a qualified diesel mechanic handle the installation.
