S&B Tanks 62 Gallon Replacement Fuel Tank for 2004-2010 GM Duramax 6.6L LLY, LBZ, LMM Crew Cab Short Bed

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.
