65 Gallon Replacement Fuel Tank 

2001-2004 6.6L Duramax LB7 Crew Cab Long Bed

• We offer tuning with calibration for the tanks through EFI Live.
  
• 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.

Do you have an Auxiliary Fuel Tank? Using these with S&B tanks will void the Lifetime Warranty.

S&B's 65-gallon fuel tank directly replaces the OEM 34-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 3 more gallons than competitor tanks, allowing you to save time, go further, and get more out of your truck! Go big or go home!

Includes a premium OEM style sending unit. ($300 value)
