The Factory CP4.2 Pump Found on 2011 and newer Duramax's has been known to be a problematic component. Even the slightest amount of fuel or water contamination can ruin the pumps internals leading to metal debris flushing throughout the entire fuel system. When these pumps fail it can lead to a repair job usually including all new injectors, fuel system sensors, fuel lines, and complete cleaning of the fuel tank and costing $8,000+. The WCFab kit is tried and true and offers some items that other kits on the market today do not. A common issue we encountered is customers installing the CP3 Pump would break the brittle cast aluminum OEM pump mount bracket, so the WCFab kit includes a stronger Billet Aluminum piece to replace it to eliminate the issue.
