Go farther between fuel stops with the S&B 64 Gallon High-Capacity Fuel Tank, designed as a direct replacement for the factory fuel tank in 2011-2019 Chevrolet Silverado and GMC Sierra 2500/3500 Crew Cab Long Bed trucks equipped with the 6.6L Duramax diesel. With nearly twice the capacity of many factory configurations, this oversized fuel tank is an ideal upgrade for long-distance driving, towing, hauling, and anyone who wants to spend less time at the fuel pump.
Engineered as a midship replacement tank, the S&B fuel tank is designed to work with the OEM fuel sending unit for reliable fuel-level operation. Heavy-duty mounting straps are included, and the tank is compatible with high-flow diesel fuel pumps found at truck stops, allowing for faster and easier refueling.
64 Gallons of Extended Range
The approximately 64-gallon capacity provides substantially more fuel than the stock tank, helping extend driving range between fill-ups. Whether you're towing a trailer across the country, putting serious highway miles on your Duramax, or simply want fewer stops on long trips, the S&B high-capacity fuel tank gives your truck the additional fuel capacity you need.
Built for Duramax Trucks
S&B engineered this tank specifically around the packaging and fuel-system requirements of GM HD trucks. The tank retains the OEM sending unit and includes the necessary mounting straps for installation. Its increased bottom surface area also provides additional fuel reserve when the low-fuel indicator illuminates.
High-Flow Fuel Station Compatible
Unlike some oversized aftermarket fuel tanks that can be difficult to fill at truck stops, the S&B 64-gallon tank is designed to accept fuel from high-flow diesel fuel pumps. Optimized venting helps provide smooth, reliable fueling without repeatedly shutting off the pump nozzle.
Fuel Gauge and Distance-to-Empty Information
The factory fuel gauge will continue to operate, but GM's distance-to-empty system cannot be reprogrammed for the larger tank. As a result, the displayed range may indicate approximately half of the truck's actual remaining range. After filling the tank, the fuel gauge may remain at full until approximately 4-5 gallons have been consumed before beginning to move normally.
