It’s designed to fit a range of trucks and provides a modular approach to extending fuel range without a full underbody tank replacement.
Key considerations include installation space, top-siphon electric pump compatibility, and weld integrity. This model is suitable for trucks needing a compact auxiliary solution with reliable seam construction. It supports standard gasoline transfer operations while maintaining a smaller footprint for easier mounting on mid-sized pickups or larger utility trucks.
RDS MFG INC Rectangular Auxiliary Fuel Tank – 69 Gallon
This 69-gallon rectangular auxiliary fuel tank from RDS MFG INC expands fuel capacity while maintaining a similar form factor to smaller tanks. It supports gasoline fueling via top-siphon with an electric pump and emphasizes sturdy construction with full-seam welding. Its larger capacity is suited for longer hauls or remote work where refueling options are limited.
Considerations for this model include the additional mounting length and weight, the top-fueling mechanism, and the overall fit for your truck bed or frame rails. The 69-gallon size balances extra range with manageable space, making it a solid option for mid-to-large pickups and utility trucks that require extended operation between fuel stops.
RDS MFG INC RDS 71789 Rectangular Auxiliary/Transfer Combo Fuel Tank and Tool
The 51-gallon combo tank from RDS MFG INC combines an auxiliary fuel tank with a tool compartment, facilitating integrated storage and fuel transfer. It supports gasoline fueling via a top-siphon electric pump and is described as a motor engine fuel tank, offering a convenient all-in-one solution for trucks needing both fuel capacity and toolbox access.
When evaluating this option, consider whether you need extra toolbox space and how the combination affects weight distribution and mounting. The integrated design can reduce the number of separate components on your vehicle, potentially simplifying installation and maintenance in fleets or individual trucks with limited space.
BLACKHORSE-RACING 60-Gal Aluminum Transfer Tank Toolbox Combo
This 60-gallon aluminum transfer tank from BLACKHORSE-RACING integrates a toolbox on the right side of the top, offering a practical combo for those who want both storage and fuel transfer capabilities. It features a 10 GPM flow rate and comes with 13.1 feet of fuel tubing for straightforward transfer to vehicles or machinery. The aluminum construction emphasizes durability and corrosion resistance for rugged use.
Key purchase points include the toolbox integration, the 10 GPM pump capability, and the length of tubing for flexible routing. It’s well-suited for construction sites, agricultural operations, and fleet applications where quick refueling and tool storage are priorities in a single package.
LAPPPLSP 60 Gallon Fuel Transfer Tank/Toolbox Combo
This 60-gallon aluminum toolbox combo from LAPPPLSP pairs a durable transfer tank with a top toolbox and a 12 GPM pump. It uses a 12V DC pump with a 13-foot hose and 6.6-foot maximum suction, suitable for transporting gasoline, diesel, or kerosene. The setup is designed for vehicles requiring reliable fuel transfer with added storage capacity for tools and accessories.
Prospective buyers should consider the power requirements, hose length, and pump efficiency in their vehicle’s electrical system. The dual-function design helps reduce the number of separate components on a truck, aiding installation and maintenance in work fleets or remote job sites.
PRUNkuar 60 Gallon Aluminum Tank Toolbox Combo With 12 GPM Pump
This 60-gallon aluminum fuel transfer tank from PRUNkuar includes a toolbox and a 12 GPM pump with a 13-foot hose. It features fully welded seams and a heavy-duty aluminum body with a 12.5A pump working current, designed for versatility with gasoline, diesel, and kerosene compatibility. The setup is suited for trucks that require robust fuel transport and quick tool access.
Evaluation considerations include pump amperage compatibility with vehicle electrical systems, the efficiency of the 13-foot hose, and the maximum suction. The combo is appropriate for fleets that prioritize an integrated storage and transfer solution in a single assembly, reducing clutter and simplifying installations on larger pickup or utility trucks.
Buying Guide: Key Purchase Considerations For Truck Auxiliary Tanks
- Capacity vs. space: Choose tank size based on typical fuel consumption, expected trip distances, and available mounting space. Larger tanks extend range but add weight and may require reinforced mounting.
- Fuel type and compatibility: Confirm the tank is rated for gasoline, diesel, or other fuels as needed, and verify pump compatibility for reliable transfer without leaks.
- Top-fueling vs. side-fueling: Top-siphon designs with electric pumps simplify refueling, while side-fueling configurations may fit certain truck layouts better. Consider ease of access and mounting orientation.
- Seam construction and durability: Welded seams improve durability and reduce leakage risk. Look for corrosion-resistant materials (e.g., aluminum) for long-term use in harsh environments.
- Toolbox integration: If on-the-go tool storage is valuable, consider combo units that include a toolbox. This can simplify installation and reduce clutter under the vehicle.
- Electrical requirements: Pump-equipped tanks demand adequate power supply. Check the pump’s amperage, wiring needs, and whether the vehicle’s electrical system can support it.
- Mounting and fit: Review dimensions and mounting hardware compatibility with your truck model. Ensure clearance for undercarriage components and exhaust or frame rails.
- Maintenance and safety: Look for sealed designs to prevent leaks, proper venting (if required), and ease of cleaning to sustain fuel quality and system safety.
- Regulatory considerations: Some regions restrict fuel storage configurations. Verify compliance with local rules and vehicle codes for auxiliary tanks in trucks and commercial fleets.
Choosing the right auxiliary tank involves balancing capacity, durability, and functional features like integrated tool storage or high-flow pumps. The options highlighted here provide a spectrum of sizes, materials, and configurations to match different truck types and usage scenarios. Always verify mounting compatibility with your specific vehicle model and consulting with a professional installer can help ensure a safe, compliant setup.
