Fleece Performance 11-16 GM 2500/3500 Duramax LML CP3 Conversion Kit w/CP3

Fleece Performance is well-known for its robust diesel performance parts, and this CP3 conversion kit for your 2011-2016 Duramax LML is a prime example. If you're looking to upgrade your fuel system beyond the stock CP4 pump, this kit offers a solid path to a more reliable and capable setup. The CP3 pump is a popular choice among Duramax owners for its proven track record in demanding applications.

This kit includes everything you need to swap your factory CP4 injection pump for a more robust CP3 pump. You'll receive the necessary adapter lines, mounting hardware, and a high-pressure fuel filter. The adapter lines are designed to connect your existing fuel lines to the new CP3 pump, simplifying the installation process. The included filter helps ensure clean fuel delivery to the pump, protecting your investment.

Upgrading to a CP3 pump can offer improved fuel pressure control, especially when running modified tuning or larger injectors. This can lead to more consistent power delivery and better overall engine performance. Fleece Performance kits are put together with attention to detail, aiming for a straightforward installation for those familiar with diesel engine work. While this is a significant upgrade, it's a well-regarded solution for Duramax owners seeking enhanced fuel system reliability and performance.
