Important Note about the 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. This occurs with all aftermarket high-capacity fuel tanks. The nozzle at high flow fuel stations (truck stops) will not be able to fill automatically. 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. Do you have an Auxiliary Fuel Tank? Read why using these with our tanks will void the Lifetime Warranty.
