2011-2016 Chevrolet GM 6.6 LML Duramax Upgraded Performance CP4 to CP3 Conversion Kit. This kit will allow the upgrade of your truck's CP4 pump to the far more reliable CP3. CP3 injection pumps are higher flowing and performance ones can support upwards of 600hp. Also allows for the removal of your factory fuel filter, further supporting the need for an upgraded fuel supply. The Duramax diesel from the factory is not supplied with a factory lift pump like other truck manufacturers. Upgrading your fuel system is a must in a Duramax!
