• 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?  using these with our tanks will void the Lifetime Warranty.
