Don't let the failure-prone CP4 pump in your Duramax leave you stranded with a several thousand dollar repair bill. When the CP4 pump fails it will send metal particles through your fuel system causing catastrophic damage to the injectors, sensors, and fuel rails.

This kit will come with everything necessary to replace your CP4 pump with a tried and true CP3 pump. Not only will you and your fuel system benefit from the reliability and peace of mind, but you will also notice an increase in performance due to the higher flow from the CP3 pump.
