S&B 56 Gallon High-Capacity Fuel Tank | 2011-2026 GMC and Chevy 2500/3500 6.6L Duramax LML/L5P Crew Cab Short Bed

Regular price $1,449.00

SKU: 10-1036

Important Notes: The nozzle at high-flow fuel stations (truck stops) will be able to fill automatically.

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. You can multiple the displayed range by 2 to find your actual range.
  • The fuel gauge will operate properly. The fuel gauge will remain on full until about 4-5 gallons have been used and then the gauge will start to move normally. 
  • 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.
