Titan Fuel Tanks specializes in upsized, aftermarket fuel tanks for diesel-powered, mid-size and full-size pickup trucks. The company’s products are made in the United States from high-density polyethylene, which is the same material many OEM fuel tanks are made out of and is “durable, flexible and crack resistant,” the company says.
Among the products on offer in the Titan Fuel Tanks catalog are 56-gallon upsized fuel tanks for the 2017-2019 model-year Chevrolet Silverado HD and GMC Sierra HD. Additionally, it recently added a 56-gallon tank for the newer 2020 model-year Chevrolet Silverado HD and GMC Sierra HD as well. Both of these tanks are designed to fit the Silverado HD and Sierra HD Crew Cab with the short, 6.5-foot bed configuration and Duramax diesel engine.
“This new General Motors tank is made of our famous military grade, cross-linked polymer (XLHDPE). It’s at least ¼” thick and built to outlast all competitors,” Titan says on its website. “It’s tougher than steel and more durable than aluminum.”
Titan Fuel Tanks told GM Authority that “there are a couple of aftermarket tuners like EFI Live that can reflash the [Silverado HD and Sierra HD] ECU to our tank size.” This will ensure the vehicle’s computer knows it has been fitted with a larger fuel tank so it does not flash error messages or experience other calibration issues after the tank is installed.
A larger fuel tank can be helpful for those who frequently drive and/or tow over long distances, thus saving them time. Larger fuel tanks are also a popular upgrade for fleet trucks and fleet vehicles for the same reason.
