The 2001-2004 GM 6.6L Duramax has a relatively restrictive factory fuel system that fails to inject the cleanest diesel fuel possible when compared to our aftermarket options. The result is prematurely worn injectors that cause a ton of unnecessary hassles down the road. Here at Alligator Performance, we offer a variety of premium aftermarket fuel systems along with other fuel accessories that will help extend the life of your injectors by providing clean fuel filtration without compromise. These complete aftermarket fuel systems come standard with both a fuel pump and water separator that filters the diesel fuel in your GM 2500HD/3500HD 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. Pair your fuel system upgrades with our Engine Upgrades and Turbo Upgrades   GM Duramax Fitments: 2001, 2002, 2003, 2004 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.
