2006-2007 GM Duramax 6.6L LBZ Fuel Upgrades
One of the biggest downfalls of the 2006-2007 GM 6.6L Duramax LBZ is its restrictive factory fuel system that fails to inject the cleanest diesel fuel possible. The result ï¿½ 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 system come standard with both a fuel pump and water separator that filters the diesel fuel in your GM 2500/3500 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 2006-2007 GM Sierra/Silverado 2500/3500.
