RDS MFG INC 71792 Rectangular Transfer Fuel Tank

The RDS MFG INC 71792 is an 80-gallon rectangular transfer fuel tank designed for auxiliary fueling. Its 50″ L x 20″ W x 19″ H footprint fits compact mounting spaces while providing substantial capacity. The unit’s aluminum construction offers corrosion resistance and lighter weight compared with steel options, contributing to easier handling during installation. It is described as an auto accessory with a United States origin, suggesting robust, locally manufactured components.
Key considerations include mounting compatibility with existing frames and the potential need for additional hardware (not always included). The product’s dimensions indicate a relatively shallow profile, which can benefit installations where vertical space is constrained. Users should verify that their vehicle’s or vessel’s mounting points align with the 50″ length and 20″ width to ensure a clean fit. The aluminum mill finish supports exposure to weather without rapid degradation.
RDS MFG INC Rectangular Auxiliary Transfer Fuel Tank

This 80-gallon auxiliary transfer tank from RDS MFG INC emphasizes domestic production with packaging specifics noting a substantial weight and dimensions suitable for larger installations. The unit is described as made in the United States, with a 48.26 cm by 50.8 cm by 127.0 cm dimensions, indicating a long, rectangular profile ideal for mounting along vehicle sides or under decks where length is available. The product’s emphasis on transfer capabilities makes it suitable for refueling diesel engines in fleet vehicles, generators, or industrial equipment.
Prospective buyers should check compatibility with existing fuel lines and fittings, as well as the availability of mounting hardware. The 80-gallon size provides ample capacity for extended operation, but space constraints and weight limits on trailers or trucks must be accounted for. The packaging weight suggests a sturdy build that can endure regular fueling tasks in demanding environments.
TRANSFERFLOW 80-Gallon Diesel Refueling Tank

The Transfer Flow 80-Gallon Diesel Refueling Tank is built to supply diesel vehicles and equipment, combining 14-gauge U.S. aluminized steel with durability suited for rugged use. The design emphasizes reliability in demanding fueling scenarios and includes practical extras such as a fuel cap, mounting kit, and instructions. This makes installation straightforward for users who want a complete package when purchasing a diesel refueling system for trucks, generators, or heavy equipment.
Considerations include corrosion resistance and long-term performance. Aluminum or steel variants offer different weight and mounting characteristics, so confirm the material choice aligns with trailer or vehicle weight limits. Since the kit includes a mounting system, verify compatibility with your mounting surface and ensure proper venting and safe fuel routing to prevent leaks during transit or operation.
Moeller Marine Products Fuel Tank, 80 gallon

The Moeller 80-gallon fuel tank emphasizes durability and United States manufacturing. While marketed within fishing equipment contexts, its capacity makes it a suitable option for marine or remote work setups requiring a reliable fuel reservoir. The product dimensions indicate a tall profile, which may be advantageous for vertical mounting with adequate clearance. The American-made claim supports expectations of standard marine-grade fittings and corrosion resistance.
Users should verify compatibility with their fuel type and mounting hardware, since marine tanks often rely on specific fittings and venting to prevent spills. Consider the installation environment—vibration, salt exposure, and temperature swings—and ensure appropriate mounting, securing, and spill containment measures are in place for safe operation.
DEE ZEE DZ91767X 80 Gallon Auxiliary Diesel Fuel Tank

The Dee Zee DZ91767X 80-gallon auxiliary diesel tank features non-rusting .125 brite-tread aluminum construction, stability baffles, and a drain plug. The combination of aluminum construction and stability features aims to minimize shifting and improve structural integrity during transport. The 80-gallon capacity aligns with heavy-duty fueling needs, making it suitable for extended trips or work sites where frequent refueling is impractical.
Considerations focus on corrosion resistance, weight handling, and the presence of a drain plug for maintenance. The brite-tread aluminum surface offers protection against wear and helps with traction in certain mounting environments. Verify the availability of installation hardware and ensure the fuel type compatibility with your vehicle or equipment’s fuel system.
Buying Guide: Key Purchase Considerations
When choosing an 80-gallon fuel tank, consider these core factors to ensure safe, compliant, and efficient operation.
- Fuel compatibility: Diesel, gasoline, or aviation fuel each require specific materials and seals. Confirm that the tank is rated for your intended fuel type and check for any venting or pickup restrictions.
- Material and durability: Aluminum tanks are lighter and corrosion-resistant, while steel variants offer robustness. Evaluate exposure to weather, salt, and road debris to select the right material.
- Mounting and fittings: Measure available mounting space and verify compatible brackets, straps, and mounting hardware. Ensure proper venting, hose routing, and leak prevention.
- Weight and load management: An 80-gallon tank adds substantial weight when full. Check vehicle or trailer gross weight ratings and axle limits to prevent overloading.
- Ease of installation: Some tanks include mounting kits and instruction sheets. If not, plan for compatible hardware and professional installation if needed.
- Maintenance features: Drains, baffles, and access ports can simplify fuel management and reduce slosh during movement. Look for drain plugs and internal baffling.
- Quality and warranty: US-made products often come with robust warranties and standardized fittings. Consider brands with established service networks for parts and support.
- Safety and compliance: Ensure mounting complies with local regulations and vehicle codes. Secure fuel tanks to minimize movement and reduce spill risk during transport.
In summary, 80-gallon tanks offer substantial fueling capacity for fleets, generators, marine, and off-road applications. Prioritize material choice, mounting compatibility, and fuel type to maximize safety, reliability, and lifecycle performance. The profiles above cover a range of common configurations to help you identify a suitable fit for your particular situation.
