Overview

The S&B 55 Gallon High-Capacity Fuel Tank is engineered specifically for Dodge Ram 2500 and 3500 models equipped with 5.9L and 6.7L diesel engines from 2006 through 2024. Designed to significantly increase your vehicle’s fuel capacity, this tank is ideal for drivers who require extended range and fewer refueling stops during long hauls or heavy-duty work. By upgrading to this high-capacity tank, you gain the convenience of carrying more fuel without compromising the reliability of your fuel system.

This fuel tank is perfect for diesel truck owners who demand durability and efficiency in demanding conditions. Whether you’re a contractor, fleet operator, or an enthusiast who spends extensive time on the road, the S&B tank offers a practical solution to maximize fuel capacity while maintaining OEM compatibility.

Key Features

Built with precision and durability in mind, the S&B 55 Gallon Fuel Tank offers several key benefits that enhance your Dodge Ram’s fuel system:

• High-capacity 55-gallon design increases fuel range significantly over stock tanks.
• Compatible with 2006–2024 Dodge Ram 2500 and 3500 diesel models with 5.9L and 6.7L engines.
• Reuses OEM sending unit and float to maintain fuel gauge functionality.
• Fuel gauge remains operational, though distance-to-empty readings will not be accurate due to tank size increase.
• Constructed to fit seamlessly with factory mounting points for straightforward installation.
• Designed with a taller profile, causing the fuel gauge to stay on full for the first 8–10 gallons after refueling.
• Not compatible with automatic shutoff nozzles at high-flow fuel stations, requiring manual fueling.
• Lifetime warranty available, with conditions regarding auxiliary fuel tank use.

Construction & Design

The S&B 55 Gallon Fuel Tank is crafted from high-quality materials engineered to withstand the rigors of heavy-duty diesel applications. Its robust construction ensures resistance to corrosion and damage from road debris, extending the life of your fuel system. The tank’s taller design optimizes fuel volume without compromising vehicle ground clearance or fitment. Precision engineering guarantees compatibility with OEM components, including the sending unit and float, preserving the integrity of your fuel gauge system.

Installation & Fitment

Installation of the S&B high-capacity fuel tank is designed to be a direct replacement for the factory tank on 2006–2024 Dodge Ram 2500 and 3500 diesel trucks with 5.9L or 6.7L engines. The tank mounts to existing factory points, simplifying the upgrade process. However, due to the tank’s increased height, expect the fuel gauge to read full for the initial 8 to 10 gallons after refueling. Additionally, automatic shutoff nozzles at truck stop fuel pumps may not function properly, requiring manual fueling to prevent overflows.

Note that using this tank in conjunction with an auxiliary fuel tank will void the lifetime warranty, so it is recommended to use the S&B tank as a standalone upgrade.
