Product Details

If you're working on a 2006-2010 GM truck with a Duramax LBZ or LMM engine, this Fleece Performance CP3 Injection Pump is a solid option for replacing your original or upgrading your fuel system. The CP3 is the heart of your diesel's fuel delivery, responsible for building the high pressure needed to spray fuel into the cylinders. When it starts to wear out, you might notice issues like hard starting, rough idling, or even a complete loss of power, especially under load.

Fleece Performance is known for building robust parts for diesel trucks, and this CP3 pump is no exception. It's built to meet the demands of these powerful engines, whether you're using your truck for daily driving, towing, or more serious work. This pump is designed as a direct replacement, meaning it should bolt up to your existing fuel lines and mounting points, simplifying the installation process. It's a well-built unit designed to restore reliable fuel pressure and keep your Duramax running strong.

When you're replacing a CP3, it's a good idea to have a few things on hand. Make sure you have new fuel filters ready to go, as you'll want to replace them after installing the new pump. Also, be prepared to bleed the air out of the fuel system once the new pump is installed. This is a critical step to ensure the pump primes correctly and avoids running dry. This pump is a significant component for your truck's performance and reliability.
