Portable Marine Fuel Tank for Outboard Engines

Built for dependable fuel transfer and safe onboard storage, this portable boat gas tank is made from rugged high-density polyethylene (HDPE) to resist aging, impact, corrosion, deformation, and harsh marine conditions such as sun exposure and saltwater. Ideal for outboard motors and small boats, it delivers a reliable on-water refueling solution for fishing trips, coastal cruising, and general marine service use.

• Dual-function vent cap: Loosen the vent screw/yellow nut during operation to release pressure and maintain smooth fuel circulation; tighten to help seal the tank for transport and storage, minimizing vapor escape and leakage risk.
• Easy to carry: Molded/I-shaped top handle provides a secure, comfortable grip from vehicle to dock to vessel.
• Fuel level visibility: Clear fuel level gauge helps monitor remaining gasoline and plan refills with confidence.
• Cleaner fuel delivery: Built-in air inlet filter helps block impurities before they reach your fuel system.
• Compact, low-profile shape: Stores neatly under many boat seats or in lockers to save deck space.
