Fuel Tank - S&B - 62 Gallon - Chevy/GMC - 2500/3500 - '11-'23 - 6.6L - Crew Cab / Short Bed
From FICMrepair.com

Want to increase the number of miles between fuel stops by 42%? This diesel 62 gallon tank from S&B will get you dramatically further than a stock 36 gallon tank ever will. 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, this tank will provide a greater fuel reserve once your "low fuel" warning comes on.

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.
WARNING: On S&B and OEM diesel fuel tanks, there are one or more rollover valves. The rollover valve uses a float/weight to close the valve when the float is immersed in fuel. This prevents fuel leakage in the event of a rollover. Gravity feed tanks or electronically controlled feed tanks can overfill the S&B or OEM tank. If/when the tank is overfilled, the rollover valves will prematurely close. Without the required vapor space in the tank, this violates the “overfill restriction” requirement of 49 CFR 393.76(12)(i). An overfilled tank can lead to a pressurized fuel tank, leaking, and tank failure.
