Description
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.

Full Tank for long trips

"Great product and an easy install. Product was shipped quickly and arrived with no concerns. Price was great compared to other sites. Only concern is GMC needs to fix the fuel gauge so it can read properly. I do have periods where I put 50 plus gallons in the tank and an hr later it drops to empty. The other issue is it reads as if it only ever has 32 gallons. Be excited to see fix for that when it comes around."

Fuel tank

"Told me the tank would be ready to ship in 4 days. Tank did not ship and staff was unable to notify me when it would be shipped. Asked for a refund and staff told me that process would take two weeks. Canceled the charge with CC company. Ordered a tank from 4 wheel truck parts was here in 5 days."

Q&A

Will this fit a 2024 duramax?
Those tanks have not been confirmed to fit the 2024 models yet.
I just purchased mine and had it installed but noticed it didn’t come with the longer float like stated in the install videos . Do you have to order that separately? I have a 21 Denali 2500
These do not require longer floats, you should be able to transfer your factory sending unit into this tank. S&B state no drilling or special modifications required. -Mark
My 2023 GMC Denali 3500 crew cab short bed has DEF fill adjacenr to fuel fill. Is this compatible???
This tank will fir on the 2023 model. It is designed to take place of the factory tank and should not cause any issues. If you have further questions please feel free to call us. -Mark
How much lower does this tank sit compared to stock? How much ground clearance do you lose?
The S&B tank sits 3.75" lower than the stock tank. -Mark
Does this tank fit a 2009 GMC Sierra HD and does it come with ALL the necessary mounting hardware?
This will not fit that year range of truck unfortunately. The only fuel tank that covers that year range for a crew cab short bed would be part number 10-1006 (as long as your truck is a crew cab short bed.) -Mark
