Industrial Injection LLY II Reman Duramax CP3+ Fuel Pump

Industrial Injection is well-known for their work with diesel fuel systems, and this LLY II Reman Duramax CP3+ Fuel Pump is a solid example of their expertise. If you're working on a 2004 or 2005 Chevrolet Silverado 2500 HD or GMC Sierra 2500 HD, this pump is designed to get your Duramax engine running strong again. It's a remanufactured unit, meaning it's been rebuilt to meet original specifications, ensuring reliable performance for your truck's fuel delivery system.

This CP3+ pump is a critical component for your diesel engine, responsible for building the high pressure needed for the injectors to work efficiently. When your original pump starts to wear out, you might notice issues like hard starting, rough idling, or a loss of power. Replacing it with a remanufactured unit like this one from Industrial Injection can restore that lost performance and ensure your truck runs as it should. The 'CP3+' designation often indicates an updated or enhanced version of the original CP3 pump, aiming for improved durability or flow characteristics over the factory part.

This pump is a direct replacement for the original equipment on your 2004-2005 Silverado or Sierra 2500 HD. It's important to note that this part is not CARB approved and cannot be shipped to California. When installing a new fuel pump, it's always a good idea to replace the fuel filters as well to prevent any debris from contaminating the new pump. Refer to the manufacturer's installation instructions for specific details and any recommended procedures.
