Duramax 6.6L L5P Fuel Contamination Kit 2017-2019 Chevy / GMC OEM Parts

Duramax 6.6L LML Fuel Contamination Kit 2011-2016 Chevy / GMC

When you have a CP4 pump fail it sends metal throughout your fuel system contaminating everything all the way into the injectors. This kit supplies all the necessary parts to repair the injection system back to 100%. We recommend flushing the filter housing and replacing all fuel filters. Add a fuel additive to increase lubrication and get your new fuel system off to a good start.
