The stock fuel system on your 2017-2019 GM Duramax 6.6L L5P fails to inject the cleanest fuel possible, leaving you with prematurely worn injectors and a ton of other hassles down the line. Here at Alligator Performance, we offer some complete premium aftermarket fuel systems along with some other fuel accessories that will help extend the life of your injectors by providing clean fuel filtration without compromise. These complete aftermarket fuel system come standard with both a fuel pump and water separator that filters the diesel fuel in your GM Sierra/Silverado to extremely low micron ratings in order to prevent contaminants from affecting your engine. If you reside in an area that sees mostly cold temperatures, you may want to check out one of the Electric Heater Kits we offer to eliminate any potential fuel gelling which makes it difficult to cold start your engine. Luckily for you, we only work with trusted and reliable brands such as FASS, AirDog, Irate Diesel and more to bring you the best possible fuel upgrades for your 2017-2019 GM 2500/3500 Truck. GM Duramax Fitments: 2017, 2018, 2019 GM 6.6L Duramax. Submodel Fitments: WT, Custom, LT, LTZ, High Country, 1LT, 2LT, Pro, SLE, SLT, AT4, Denali. Some exceptions apply, please see individual product pages for specific fitments.
