Attwood 8806LP2 Epa Certified 6 Gallon Portable Fuel Tank
Capacity and compliance meet both EPA and CARB regulations, making this tank a solid choice for small boats and marine setups. The built-in vacuum valve eliminates the need for manual venting, simplifying refueling at the dock or on the water. Best for boat owners who prioritize regulatory compliance, ease of venting, and compact, portable design. A potential limitation is its 6-gallon size, which may require more frequent refills on longer trips.
DEF Portable Boat Fuel Tank, 6gal
Made from high-density polyethylene, this 6.3-gallon marine tank resists aging, impact, and corrosion. It features dual sealing modes and a vented option to ensure smooth fuel flow and minimize leaks. An integral oil volume indicator helps track remaining fuel, and a built-in inlet filter protects fuel quality. Choose this if you need a robust, expandable sealing system and a visual fuel gauge for marine refueling. Limitation: the dual-cap design may require familiarization to operate both modes properly.
Amenitlif 14.5 Gallon Marine Portable Tank
This larger marine tank provides substantial capacity for longer trips or higher fueling needs. It includes an I-shaped handle for easy carrying and a fuel level indicator with an integrated filter to maintain fuel cleanliness. Best for boaters who require extended range and straightforward transport. Limitation: higher capacity means heavier handling when full, which could affect maneuverability on small vessels.
MOTO4U Auxiliary Gas Fuel Tank (2L)
Designed for motorcycles and light vehicles, this 2-liter auxiliary tank provides a compact option with a hose and cut-off valve for controlled flow. Best for riders needing a small, portable fuel reserve and easy installation. A caution is that its small capacity may require frequent refueling on longer rides or under aggressive power use.
TAURISH Auxiliary Fuel Tank Workshop Tool
Intended as a workshop tool for carburetor balancing and tuning, this 300 ml tank includes embossed fuel lines and a handy strap for secure placement during engine work. Best for DIY servicing and tuning work where a precise, small-volume fuel source is advantageous. Limitation: limited capacity makes it unsuitable for regular refueling during outdoor use.
ekurfos Mini Motorcycle Fuel Tank
With a 1.5-liter capacity, this mini tank includes a fuel line and threaded cap to prevent leaks during tilting or vibration. It is built from thickened plastic for impact resistance and aging durability. Best for small bikes, ATVs, and other compact engines requiring a safe, spill-resistant auxiliary fuel solution. Limitation: small capacity may not meet higher fuel demands on extended rides.
Porotmotor Motorcycle Auxiliary Fuel Tank (500ml)
Intended for small-engined work and carburetor tuning, this 500 ml auxiliary tank enables precise fuel testing and direct delivery to the carburetor. Best for hobbyists and professional mechanics performing tuning tasks. A limitation is its very small capacity, which is not suitable for general fueling on vehicles.
Buying Guide
What to consider when choosing a plastic auxiliary fuel tank:
