Scepter 12 Gallon Portable Marine Gas Can
This 12-gallon tank offers ample capacity for longer trips on outboard-powered pontoon boats. It includes a 2-way vented cap that allows air flow during refueling and releases pressure above 5 PSI to prevent vapor buildup. A built-in gauge helps you check fuel level quickly. The tank accepts standard 1/4 NPT marine fittings. Best for boaters needing extra endurance without frequent refueling, especially on bigger pontoons. Caution: ensure fuel line connection is compatible with your engine’s fittings and use the appropriate hoses (sold separately).
VEVOR Marine Tank 14.53 Gal
This 14.53-gallon tank provides high capacity with a visible gauge and a 9.8 ft hose, enabling easy remote fueling. The separate inlet and outlet reduce spillage, and the tank is built from high-density polyethylene for resilience against aging, impact, and corrosion. It’s ideal for anglers or cruisers needing more fuel on extended days away from shore. Best for boats that require a longer reserve; avoid prolonged sun exposure to protect the tank’s material integrity. Compatibility is strongest with Yamaha connectors through the supplied hose.
Scepter 9 Gallon Portable Marine Gas Can
The 9-gallon variant offers a compact footprint with a built-in gauge and 2-way venting for safe refueling. It’s suited for smaller pontoon setups or boats with limited storage space while still providing a reliable fuel capacity for longer days on the water. Best for boats where space is at a premium; consider the smaller size if you frequently troll for perch or need lighter handling. Limitation: gauge readability may be less prominent in bright sun; store in shade when possible.
Scepter 08669 Rectangular 12 Gallon Low Profile Tank
This 12-gallon rectangular tank is designed to fit in tighter spaces with a low-profile profile, making it a strong choice for pontoon layouts with under-seat storage or narrow walkways. The vented cap helps with safe refueling, and the built-in gauge assists quick checks. Best for pontoons where vertical clearance is limited; consider width and height to ensure fit under seating or consoles. A potential limitation is space in models with very compact storage compartments.
Attwood 12 Gallon LPG2 Portable Tank
Attwood’s 12-gallon LPG2 combines automotive-grade multi-layer construction with an automatic vacuum valve for steady fuel flow. It’s EPA and CARB certified, suitable for pontoon boats that require robust performance across varied conditions. Best for boaters seeking durable construction and reliable venting; avoid if you need a tank with the absolute smallest footprint. Note: valve design reduces manual venting needs, simplifying operations on moving water.
Attwood 12 Gallon Portable Marine Fuel Tank With Gauge
Another Attwood option combines a 12-gallon capacity with gauge visibility and a vacuum valve for consistent flow. It’s designed for pontoon boats where higher fuel capacity reduces refueling intervals. Best for multi-day trips or family boats. Limitation: ensure compatibility with your engine’s fittings and hoses; check the gauge readability under sun glare.
Buying Guide
What capacity should you choose?
Pick based on typical cruise length and engine demand. Larger pontoons or longer trips benefit from 12–14.5 gallon tanks, while smaller vessels may be comfortable with 9 gallons.
Is a built-in gauge important?
Yes for quick fuel checks on the water. Tanks with a gauge help you estimate remaining range without opening the fill cap.
How important is venting and safety?
2-way vented caps prevent dangerous vapor buildup and enable safer refueling. Auto vacuum valves remove the need for manual venting.
What about space constraints?
Low-profile designs fit tight storage areas. Measure available space before purchasing to avoid fit issues under seats or consoles.
Durability and materials?
Look for high-density polyethylene (HDPE) with UV stabilization for marine environments and resistance to corrosion from salt spray.
