Designed to fit like factory while delivering nearly double the fuel capacity, the S&B 56-Gallon Tank gives your Duramax the range to go farther between fill-ups. Built to utilize the OE footprint, this high-capacity tank maintains ground clearance and integrates cleanly with your truck—perfect for towing, road trips, and long days on the job.
Built for faster fill-ups, the S&B 56-Gallon Tank is designed to work with high flow fuel pumps commonly found at commercial fueling stations. The integrated oversized fill neck helps reduce pump shutoff issues and allows fuel to flow smoothly into the tank, getting you back on the road quicker.
Important Notes: The nozzle at high-flow fuel stations (truck stops) will be able to fill automatically.
-
The distance to empty (DTE) on GM trucks can’t be reprogrammed, so it will show about half the mileage that is really left. You can multiple the displayed range by 2 to find your actual range.
- The fuel gauge will operate properly. The fuel gauge will remain on full until about 4-5 gallons have been used and then the gauge will start to move normally.
-
The bottom of the S&B tank has more surface area than the OE, so there will be a greater fuel reserve when the low fuel indicator comes on.
