Make sure you maintain the fuel system in your 2011-2016 Chevy/GMC 6.6L LML Duramax with the correct Fuel Filter. Frequent fuel filter changes are especially important when it comes to protecting your fuel injectors, fuel pumps, and engine. Use a stock replacement or aftermarket filter constructed with premium filter media to ensure you get proper filtration efficiency. Shop manufacturers like AFE, Racor, Dorman, Motorcraft, ACDelco, and more to get the Fuel Filters and accessories your vehicle needs.
