ALMOST DOUBLE YOUR RANGE.
S&B's 68-gallon fuel tank directly replaces the OEM 36-gallon tank without any cutting, drilling, or special modifications. This makes for a trouble-free, faster installation process. S&B's replacement fuel tank holds 8 more gallons than competitor tanks allowing you to save time, go further, and get more out of your truck!
HIGH STRENGTH MATERIAL
The S&B Tank sits 3.75" lower than the stock tank and is made out of a high strength cross-linked polyethylene material.
LOCKED IN FOR A TRUE SEAL.
The S&B Fuel Tank was designed to use the OEM locking ring. This ensures a perfect seal and securely retains the fuel pump onto the tank.
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 fuel gauge will operate properly. When you fill up your tank, the fuel gauge will remain on full until about 4-5 gallons have been used and then the gauge will start to move normally. GM trucks monitor for an inoperative fuel gauge, so in some situations, until it starts to move, the truck’s computer will drop the gauge to empty to get the driver’s attention even though your tank is full. The gauge will return to its normal position after restarting the engine. Once the fuel level drops 4-5 gallons from full, the fuel gauge will return to its normal operation.
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.
The nozzle at high-flow fuel stations(truck stops) will not be able to fill automatically.
