S&B 10-1023 62-Gallon Replacement Fuel Tank for 2001-2004 GM Duramax LB7

S&B 10-1023 for Duramax LB7

The S&B 10-1023 is a 62-gallon midship replacement fuel tank specifically designed for 2001-2004 Chevrolet Silverado and GMC Sierra 2500/3500 Crew Cab Short Bed trucks with the 6.6L Duramax LB7 diesel engine. Replacing the factory 26-gallon tank, it offers an extended fuel capacity for fewer stops and longer driving ranges, all without cutting, drilling, or special modifications.

Durability and Construction
Built from Crosslink Polyethylene, this tank is engineered for durability and resistance to wear. Its lightweight design, weighing 62 lbs dry, ensures easier installation. With dimensions of 79.25" x 17.74" x 20.82", it provides a seamless fit, although it lowers ground clearance by 5 inches compared to the OEM tank.

Enhanced Functionality
The tank features a built-in sump for aftermarket lift pump installations and is transfer pump ready. It includes a premium OEM-style sending unit valued at $300, ensuring accurate fuel monitoring. The tank’s baffled interior reduces sloshing and ensures consistent fuel delivery. While the tank integrates seamlessly with your truck, the distance-to-empty gauge cannot be recalibrated on GM trucks and will display half the actual mileage remaining.

Compatibility and Warranty
This fuel tank is compatible with 2001-2004 LB7 engines only and does not fit later models like LLY, LBZ, or LMM. It comes with a lifetime warranty, but usage with auxiliary fuel tanks will void the coverage. This tank is ideal for those seeking extended range and reliable performance in their Duramax-powered vehicles.
