VEVOR Portable Diesel Tank, 58 Gallon Capacity

The VEVOR unit features a robust black polyethylene tank with a lockable lid and a 12V transfer pump delivering about 10 GPM. Its 58-gallon capacity suits frequent refueling on longer jobs without constant tank recharges. The built-in mechanical fuel gauge helps monitor diesel levels, supporting timely refills. An upgraded duplex filter aims to improve fuel purity by catching larger particles before they enter the pump. Best for road crews or remote sites where security and sustained operation matter. Caution: gatekeeping features add cost and weight; ensure the lock is compatible with your security needs.
Vigorighter 51 Gallon Aluminum Tank Toolbox Combo

This unit blends a 51-gallon aluminum fuel tank with a built-in toolbox, offering a compact footprint for limited truck bed space. The aluminum construction emphasizes corrosion resistance and durability in harsh conditions. A 12 GPM, 13-foot hose, and auto-shutoff nozzle provide quick, spill-free refueling in the field. Best for users who need tool storage alongside fuel capacity, especially in work crews that require on-site maintenance. Limitation: aluminum can dent under heavy impact; verify mounting clearance in tight spots.
PRUNkuar 60 Gallon Aluminum Tank Toolbox Combo

PRUNkuar combines a 60-gallon aluminum transfer tank with a heavy-duty toolbox, plus a 12 GPM pump and a 13-foot hose. The setup prioritizes spill prevention with an auto nozzle, and the toolbox provides a practical staging area for wrenches, fittings, and small parts. Best for professionals who need a multi-functional unit that keeps fuel and tools in one heavy-duty package. Limitation: assembly and fitment require careful alignment to vehicle beds; confirm dimensions before purchase.
PRUNkuar 51 Gallon Fuel Transfer Tank Tool Box Combo

This unit pairs a 51-gallon aluminum transfer tank with a toolbox and includes a 12V DC pump and auto fueling nozzle with a 13-foot hose. The combination supports organized storage and straightforward fueling on the job site. Best for crews needing a compact, ready-to-use system with storage capability. Caution: smaller capacity than some users require; plan for refueling intervals accordingly.
RDS MFG INC 69 Gallon Rectangular Tank

This 69-gallon rectangular auxiliary tank emphasizes fully welded seams and a robust, compact form factor designed for broader capacity in limited spaces. It accepts gasoline fueling via an electric pump, fitting some short-bed configurations with careful measurement before ordering. Best for users who need more capacity in a rectangular footprint and straightforward top-access fueling. Limitation: higher capacity can add weight; ensure vehicle capabilities align with load requirements.
Buying Guide
- Capacity vs. vehicle fit: Choose a capacity that aligns with typical fueling intervals and your vehicle bed size. Larger tanks offer fewer refuels but add weight and space considerations.
- Material and durability: Aluminum tanks resist corrosion but may dent; polyethylene tanks excel against weather and UV exposure but can be heavier. Select based on environment and impact risk.
- Pump type and flow rate: A 12V DC pump with 10–12 GPM is common and efficient for most trucks. Higher flow is faster but may require more robust wiring and safety considerations.
- Integrated toolbox or accessory storage: If tool storage is important, models with toolboxes save space but may limit internal tank dimensions. Confirm overall footprint.
- Seals, filters, and filtration: Duplex filters and robust seals help prolong pump life and keep fuel clean. Check for easy maintenance and replacement parts.
- Security and safety features: Lockable lids, auto-nozzles, and spill-prevention accessories reduce risk but add cost. Ensure compatibility with your site’s security needs.
- Installation and compatibility: Some units fit short-bed trucks or particular bed widths. Always verify dimensions and mounting options before purchase.
