Tuning required after install. Choosing to convert your failed CP4 fuel pump to the earlier model CP3 fuel pump can be a big job. Let us help you with the conversion by providing you with everything you need to replace the contaminated parts with genuine OE parts including a brand new CP3 (no core required). When disaster strikes we are here to help you get your Duramax up and running with the reliable CP3 fuel system components.
