Save Time. Go Further. Get More Out of Your Truck. Being stuck with the OEM 36 gallon tank isn't fair. You spend more time looking for fuel stations, are stuck paying high fuel prices, and are slowed down by this inconvenience.
Do you have an Auxiliary Fuel Tank? Read why using these with our tanks will void the Lifetime Warranty.
The fuel gauge will continue to work however the distance to empty will not be accurate. There is not a way to update the fuel tank size for the distance to empty to be accurate. The fuel gauge will remain on "F" for a bit longer because of the fuel above the float. The float's empty position in the S&B Tank is the same as the OEM tank. Since the bottom surface area on the S&B Tank is larger, the 62 Gallon tank with have a greater fuel reserve.
Note: GM trucks monitor for an inoperative fuel gauge. When the truck thinks there is a problem it will drop the gauge to empty to get the driver’s attention. High capacity fuel tanks may cause the truck to think there is a problem because the fuel level sensor float arm moves slower than stock. If this happens, the gauge will return to its normal position after restarting the engine.
