Trailfx Trail FX 37024151 100 Gallon Rectangle Fuel Transfer Tank

The Trailfx 100 Gallon Rectangle Fuel Transfer Tank is built for rugged use with extra heavy-duty aluminum tread plate. It includes a lockable cap for security and a recessed drain to simplify maintenance. This model is best for off-road fleets, ranchers, and contractors who need a sturdy, portable solution for frequent refueling. The lockable cap reduces theft risk, and the recessed drain helps manage spills during transfer. A potential limitation is the aluminum weight when fully filled, which may affect mounting choices on lighter vehicles.
Weather Guard 100-Gallon Rectangle Fuel Tank

The WEATHER GUARD 100-Gallon Tank is designed to handle diesel and hydraulic fluids in a pickup setting. It emphasizes corrosion resistance with a sturdy exterior and a practical capacity for frequent long-haul refueling. It is best for customers seeking a robust, non-flammable fluid transfer system compatible with typical pickup setups. A limitation is the requirement to strictly use non-flammable fluids, which may constrain certain industrial uses.
Tradesman 83010T 100-Gallon Steel Tank

Tradesman’s 100-Gallon steel storage tank features a rugged 14-gauge exterior with a texture black powder coat for corrosion protection. Its radius curves help relieve weld stress, making it a reliable choice for heavy-duty trucking and fleet maintenance. This tank is best for operators prioritizing steel durability and a traditional appearance. A potential drawback is the heavier weight of steel, which can complicate installation in smaller vehicles or tight spaces.
Dee Zee DZ91753SB (106 Gallon) Rectangle Transfer Tank

The Dee Zee DZ91753SB provides a durable 106-gallon steel transfer solution with a black finish and corrosion protection. It is best for users who want a slightly larger than 100-gallon option with metal construction and a clean exterior. The main limitation is the extra capacity beyond 100 gallons, which may not be necessary for all operations and could affect weight distribution on smaller pickups.
VEVOR Portable Diesel Tank 116 Gallon

The VEVOR 116-gallon portable diesel tank uses high-quality polyethylene, UV resistance, and a lockable lid for security. It features a 12V transfer pump and a duplex filter for purer diesel, with a capacity suited for large refueling tasks. Best for users who need maximum capacity and enhanced filtration. However, its 116 gallons exceed the 100-gallon target, which may be unnecessary for smaller operations and could impact transport stability on compact vehicles.
Buying Guide
What capacity best fits your needs?
While all options revolve around approximately 100 gallons, consider whether you need a strict 100-gallon capacity or if a slightly larger tank would streamline refueling for your workflow. Heavier steel tanks add durability but increase weight. Lighter polyethylene tanks are easier to mount but may be less rugged in abrasive environments.
Material choice: steel vs. aluminum vs. high-density polyethylene
Steel tanks, like the Tradesman and Dee Zee models, excel in rugged durability and impact resistance. Aluminum tanks, such as Trailfx, are lighter and resist corrosion but can cost more. Polyethylene tanks (VEVOR options) are corrosion-resistant and lightweight, with integrated filtration options for cleaner fuel. Choose based on mounting constraints, terrain, and maintenance practices.
Security and spill management
Look for a lockable cap and secure lids to reduce theft and spills. Recessed drains simplify cleaning and discharge control. Consider duplex filtration to keep impurities out of your fuel system, which is especially important for off-road or remote fueling scenarios.
Compatibility with fluids and vehicles
Check whether the tank is approved for diesel, gasoline, or hydraulic fluids and ensure it matches your vehicle’s mounting points and clearance. Some models specify non-flammable fluids only, which can limit use cases in certain industries.
Installation and maintenance considerations
Portability, mounting hardware, and compatibility with pumps are essential. If you need quick deployment on various sites, prioritize lighter, easily portable designs with straightforward pumps. For permanent installations, a heavier steel tank may be more cost-effective over the long term.
