Scepter 12 Gallon Portable Marine Gas Tank
The Scepter 12 Gal tank is designed for boats needing longer running time on a compact form. Best for mid-size pontoon boats that require more fuel capacity without adding bulk. It includes a built-in fuel gauge and a 2-way vented cap to manage vapor buildup during refueling. The tank is compatible with diesel and ethanol-blended fuels, broadening fuel options for regional boating setups. The included pickup supports quick fuel checks, while standard 1/4 NPT fittings ensure common marine connections. Caution: avoid prolonged exposure to direct sunlight to minimize aging and expansion.
VEVOR Marine Tank 14.53 Gal
This tank offers a larger capacity (14.53 gal) with a clear gauge and a long 9.8 ft hose, making it a solid choice for outboard-equipped pontoons and yachts. Best for boaters who want extended running time and easier remote fueling. Its high-density polyethylene construction is designed to resist aging and corrosion. The separate inlet/outlet helps minimize spills. Note: avoid direct sunlight for extended periods to reduce aging and expansion risks.
Scepter 9 Gallon Portable Marine Gas Can
The 9-gallon Scepter option suits smaller pontoons or as a supplementary tank for longer trips. It features a 2-way vented cap and a built-in fuel gauge for quick checks. Best for boaters seeking a compact yet reliable fuel solution with EPA/CARB compliance. A potential limitation is lower capacity compared to larger tanks, which may require more frequent refueling on long cruises.
Scepter 08669 Rectangular 12 Gal Low Profile
This low-profile 12-gallon tank is ideal for pontoon setups with tight under-seat or rear compartments. It keeps a slim footprint while offering the same built-in gauge and vented cap as larger models. Best for pontoon layouts where height clearance matters. Caution: ensure mounting orientation follows the manufacturer’s guidance to maintain vent and gasket integrity.
Attwood 6-Gallon Portable Marine Tank
Attwood’s 6-gallon option is compact yet engineered for resilience with an automatic vacuum valve for consistent fuel flow. Best for pontoons needing dependable, space-conscious tanks with dependable valve technology. This tank’s smaller capacity can be a limitation for longer trips, but its robust construction suits heavy usage environments and rough seas.
Attwood 12 Gallon Portable Marine Tank
This 12-gallon Attwood tank is a strong option for pontoon boats requiring more fuel capacity without adding bulk. It features automotive-grade multi-layer construction and an automatic vacuum valve to maintain steady fuel flow. Best for longer trips and vessels that operate in variable conditions. Limitation: ensure the tank’s venting remains unobstructed to prevent pressure build-up in storage.
Buying Guide
- Capacity vs. space: Larger tanks provide longer run times but may not fit under seats or behind railings. Measure available space before selecting capacity.
- Ventilation system: Vented caps help prevent vapor buildup; ensure the model has a robust two-way vent to improve refueling safety.
- Fuel gauge and visibility: Built-in gauges save time checking fuel. Decide if you prefer sight gauges or external indicators for quick level checks.
- Material and durability: High-density polyethylene tanks resist corrosion and aging. Look for UV stabilization if exposed to sun.
- Compatibility and fittings: Check compatibility with Yamaha or other connectors if you use specific outboard engines. Confirm included hose length or plan to buy separately.
- Weight and handling: Consider molded handles and overall tank weight for easy transport on deck or dockside.
- Safety and compliance: EPA and CARB compliance is important for cleaner fuel handling and regional regulations.
