Designed with performance builds in mind, this 56-gallon high-capacity fuel tank is fully compatible with S&B Traction Bars—giving you the clearance and fitment needed without compromise. Whether you're towing heavy, launching hard, or daily driving, the tank and traction bars work together seamlessly to maximize strength, stability, and fuel capacity. No cutting. No guesswork. Just a clean, integrated fit built specifically for your GM Duramax.
Important Notes: The nozzle at high-flow fuel stations (truck stops) will be able to fill automatically.
Fuel Gauge Operation:
-
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.
