Upgraded Performance CP4 to CP3 Conversion Kit

This kit will allow you to upgrade your truck to the far more reliable CP3 and rid yourself of the factory CP4 pump. CP3 injection pumps are higher flowing and performance ones can support upwards of 600hp!**

It is highly recommended that you add a lift/supply pump when doing this upgrade, especially if you are also adding a performance fuel pump…DONT STARVE YOUR CP3!

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!

This kit also allows for the removal of your factory fuel filter, further supporting the need for an upgraded fuel supply.
