Note: Several products here are designed to support 200-gallon capacity through modular configurations or by pairing smaller tanks. When selecting a tank, consider mounting availability, compatibility with your truck model, and maintenance needs. The following sections detail five relevant options, emphasizing who benefits most and why each was selected.
LEE DT 200 Diesel Fuel Tank
Capacity: 200 gallons. Construction: 10-gauge steel. Compatibility: Truck and forklift use. Features include a standard fuel cap and gauge for quick level checks, forklift rails on top and bottom for transport, and bolt holes on the flanges for securing the tank or linking multiple tanks for added storage.
Best for: Operators needing a single high-capacity tank with straightforward mounting and easy fuel monitoring. This unit is well-suited for fixed installation on a service truck or yard vehicle that requires reliable, readily visible fuel levels in a rugged steel shell.
Caution: Steel construction is durable but may require corrosion protection and regular maintenance in extreme environments.
LEE DT 2×100 Diesel Storage Tank
Capacity: 200 gallons total (two 100-gallon compartments). Construction: Rugged steel with dual caps and gauges. Features include forklift rails, transport-ready design, and bolt holes for secure mounting or chaining multiple tanks.
Best for: Fleets that want modular storage, allowing rapid swapping or staging of two separate tanks in a single footprint. This is ideal for multi-site operations or where fuel sourcing varies by location.
Caution: Dual compartments require careful balance and securing to prevent movement on rough roads during transit.
RDS Aluminum Auxiliary Tank 200 Gal
Capacity: 200 gallons. Design: Aluminum, rectangular, smooth. Features include a baffled interior to prevent sloshing, a sight gauge for easy level reading, and a 6-inch inspection clean-out port for maintenance access.
Best for: Operators needing reduced weight with corrosion resistance and stable fuel flow in heavy-usage scenarios. The sight gauge helps quick checks, excellent for long trips where fuel planning is critical.
Caution: Aluminum tanks require proper sealing and corrosion considerations in salt-exposure environments.
RDS MFG INC Fuel Tank – 60-Gallon
Capacity: 60 gallons. Note: RDS offers a full assortment of tanks to fit various needs and bed configurations. This model supports gasoline auxiliary fueling via top siphon with an electric pump, and is suitable for shorter bed applications after measurement.
Best for: Buyers needing a compact auxiliary tank with compatible accessories for smaller truck beds or supplemental fueling on limited space.
Caution: Not a 200-gallon unit; consider as a supplementary option within a broader fueling strategy.
RDS MFG INC – 72548 Fuel Transfer Tank/Toolbox Combo
Capacity: 60 gallons in a toolbox-combo configuration. Features include a toolbox integrated with a fuel transfer capability, designed for versatile on-truck storage. The item is categorized as Auto Accessory, with dimensions hinting at a combined footprint suitable for certain truck bed layouts.
Best for: Operators seeking an integrated storage and fueling solution in a single module, particularly when workshop tools and fuel access are needed in the same unit.
Caution: This model does not provide a 200-gallon capacity; consider it for space-saving configurations alongside larger tanks.
RDS MFG INC Rectangular Auxiliary Fuel Tank – 69 Gal
Capacity: 69 gallons. Notes: RDS offers a range of tanks; this model supports gasoline auxiliary fueling via top siphon with electric pump. Package dimensions provide a sense of its fit on various truck beds.
Best for: Buyers needing a compact mid-range auxiliary tank with easy fueling and installation in restricted spaces.
Caution: Not a 200-gallon unit; suitable as part of a modular fueling setup rather than primary long-range storage.
VEVOR Portable Diesel Tank — 58 Gal
Capacity: 58 gallons. Design: Portable, polyethylene construction with a 12V transfer pump, 13.1-foot hose, and an auto-nozzle. Features two filters to remove impurities and a lockable lid for security. Flow rate is 10.6 GPM with a 140W pump power.
Best for: Field fueling or emergency backup where portability and quick deployment matter. Good for remote job sites or backup supply scenarios.
Caution: Not a stationary tank; consider storage and handling when used on moving vehicles or in transit situations.
Buying Guide
What capacity fits your needs?
For steady, long-haul patterns, 200 gallons can reduce refueling stops, but space, weight, and mounting constraints matter. Consider whether you want a single large tank or modular units that can be rearranged.
What mounting and compatibility should you verify?
Check truck bed dimensions, frame mounting points, and any forklift-related hardware. If the vehicle requires dual tanks or stacking options, confirm bolt patterns and load balance.
Material choices — steel vs. aluminum vs. plastic
Steel tanks offer durability and strength but require corrosion considerations. Aluminum tanks save weight and resist corrosion but may be pricier. Polyethylene options are lightweight and portable but may have different pressure tolerances.
Fuel management features
Look for built-in gauges, sight indicators, and secure caps. Slosh prevention (baffles) improves stability when the vehicle moves, especially with larger capacities. Consider a tank with an inspection port for maintenance access.
Portability and accessories
Portable tanks (like the VEVOR 58-Gallon) suit temporary fueling needs or backup supplies. For on-truck applications, integrated toolboxes and transfer pumps can save space and improve workflow.
Installation and maintenance considerations
Ensure compliant mounting hardware, leak-proof seals, and periodic inspection of hoses and fittings. Plan for routine cleaning and checks of gauges and caps to maintain accurate fuel readings.
