S&B 10-1010 65-Gallon Replacement Fuel Tank for 2004-2010 GM Duramax

S&B 10-1010 for Duramax LLY, LBZ, and LMM

The S&B 10-1010 is a 65-gallon midship replacement fuel tank designed for 2004-2010 Chevrolet Silverado and GMC Sierra 2500/3500 Crew Cab Long Bed trucks with 6.6L Duramax engines (LLY, LBZ, and LMM). Replacing the factory 34-gallon tank, it nearly doubles fuel capacity, providing extended range without cutting, drilling, or special modifications during installation.

Durability and Features
Constructed from Crosslink Polyethylene, this tank offers exceptional durability and resistance to deformation. Weighing 50 lbs when dry, its precise fit ensures easy installation and minimizes the impact on ground clearance, which is reduced by 5-7/8 inches compared to the OEM tank. S&B’s design includes three more gallons than competitor tanks, maximizing capacity for extended trips.

Enhanced Performance
The tank comes with a premium OEM-style sending unit, valued at $300, ensuring accurate fuel level readings. It integrates seamlessly with your truck’s system, although GM trucks do not support recalibration of the distance-to-empty feature, which will display approximately half the actual mileage. This tank’s baffling minimizes fuel sloshing and enhances performance, making it transfer pump ready for convenient use.

Compatibility and Warranty
Designed for 2004-2010 Duramax LLY, LBZ, and LMM engines, this tank is not compatible with OE skid plates but includes all necessary straps for installation. Backed by a lifetime warranty, it provides peace of mind, though the warranty is voided if used with auxiliary fuel tanks.

This 65-gallon tank is the ideal solution for those seeking increased fuel capacity and improved efficiency for long hauls and heavy-duty applications.
