S&B 62-Gallon Replacement Fuel Tank for GM Duramax

The S&B 62-Gallon Replacement Fuel Tank is designed to dramatically extend driving range for GM Duramax trucks while maintaining factory-level fitment and reliability. This high-capacity tank replaces the OEM fuel tank, providing significantly more onboard fuel without sacrificing ground clearance or drivability.

Constructed from S&B’s proprietary cross-linked polymer, the tank is built to resist impacts, corrosion, and harsh operating environments far better than traditional steel tanks. It integrates seamlessly with factory fuel system components and is engineered to retain proper fuel pickup and gauge functionality, making it a dependable upgrade for towing, long-distance travel, and work applications.
