VEVOR Boat Fuel Tank, 3.17-Gallon
This compact transfer tank is designed for outboard adventures and small to mid-sized boats. It includes a long 9.8 ft/3 m hose with a 0.24″/6 mm inner diameter, making it compatible with common Yamaha connectors and similar setups. The 3.17 gal/12 L capacity suits auxiliary fueling or topping off at the dock. Best for anglers, deck boats, and portable refueling on a boat deck where space is limited.
Best for: boaters needing a small, portable transfer option that fits under seats or in a tight locker. The molded top handle facilitates transport from dock to boat.
Limitation: Prolonged sun exposure can age the polyethylene and risk expansion, so store out of direct sun when possible.
Automatic Electric Fuel Transfer Pump with Auto-Stop
This pump uses an auto-stop sensor to halt flow when the destination tank is full, minimizing spills. It’s powered by 4 AA batteries or a USB-C source, enabling portable fueling anywhere. It includes a hose and adapters for various can sizes. Best for: quick, spill-free top-offs on the go, especially when access to a power outlet is limited.
Limitation: Some cans or interfaces may be incompatible; check the adapter kit and container type before use.
LAUCO Portable Marine Fuel Tank
With a 6.34 gal/24 L capacity, this tank offers robust carrying capacity for mid-size boats. It features a 9.8 ft/3 m hose (0.3″/8 mm inner diameter) and a dual-cap design allowing sealed or vented operation to reduce leakage risk during transfer. Best for: boaters who need more fuel on board without frequent refills and who value a secure cap design to minimize drips.
Limitation: A larger tank means more weight and storage space; ensure your vessel has adequate space for transport and use.
Steauty 12V 75W Fuel Transfer Pump Kit
This portable DC pump can move up to 110 GPH with a suction reach of 39 inches. The integrated kit includes hoses and essentials, packaged in a compact case for easy transport. Best for: users who want a complete, ready-to-use fueling solution for vehicles, boats, and equipment, without buying extra parts.
Limitation: Requires a power source (12V battery or compatible supply). Not ideal where power is unavailable for extended periods.
Vierkate 5GPM Cordless Pump
This cordless system runs on compatible DeWalt 20V or Milwaukee 18V batteries, delivering up to 5 GPM. It includes a 51″ hose and adapter assortment for multiple can sizes. Best for: larger refueling tasks where battery-powered flexibility and auto-stop safety matter, such as on larger boats or remote docks.
Limitation: Battery compatibility is essential; ensure you own or can obtain the approved battery platform and keep spares charged for longer trips.
FACFUEL 12V Electric Pump Set
The FACFUEL set features a 30 GPH pump with a pulley head conduit to reach beneath curved tanks. It comes with high-elastic hoses, power cords, and secure carrying case. Best for: diversified fueling tasks in boats and other equipment, with ready-to-pack components for travel or storage.
Limitation: Lower flow rate than some high-capacity pumps; plan for longer fueling times on larger tanks.
SENBOWE Automatic Fuel Transfer Pump
This model blends auto-stop sensing with a four-adapter kit to fit most standard cans. It can transfer at up to 4.2 GPM and works with diesel, gasoline, engine oil, and kerosene. Best for: users seeking a versatile pump that can handle multiple fuels with a clear auto-stop function for safety.
Limitation: The four adapters may require verification for your specific can neck size; otherwise, compatibility is broad.
Buying Guide
What size tank do I actually need?
Choose capacity based on typical fueling intervals, boat size, and storage space. Small boats benefit from 3–6 gallon options; larger tenders or multi-crew vessels may require 12–24 liter or higher tanks with longer hoses.
What about hoses and fittings?
Look for hoses with inner diameters that match your fuel can outlets and outboard connectors. Longer hoses offer flexibility but add weight and potential handling complexity. Sealed or vented cap designs reduce leaks.
Is auto-stop important?
Auto-stop sensors prevent overfill and spills, especially when topping off from a portable can. If you will refuel away from docks, consider models with reliable auto-stop and spill-prevention features.
Power options and portability
Cordless pumps offer maximum flexibility but depend on batteries. Cable-powered or USB-Charged units require a power source. For on-board use, consider 12V options with a compact footprint.
Compatibility and safety considerations
Verify compatibility with your can neck, fuel type, and boat layout. Securely sealing caps and durable materials extend lifespan in marine environments. Always store fueling gear out of direct sun and away from heat sources.

Frequently Asked Questions
- What is the typical capacity I should choose for a small boat? – A capacity of 3–6 gallons is usually sufficient for auxiliary fueling on small boats or decks.
