Scepter 12 Gallon Portable Boat Gas Tank
Capacity: 12 gallons. This tank provides ample fuel for longer runs while remaining relatively compact for boat storage. It includes a built‑in fuel gauge and a 2‑way vented cap that allows air flow during refueling while automatically releasing pressure after 5 PSI to prevent vapor buildup. It’s compatible with diesel and ethanol‑blended fuels and accepts standard 1/4 NPT marine tank fittings. Best for boaters who want visibility of fuel level and a built‑in gauge for quick checks. Caution: ensure the fuel line connection is correctly installed to avoid leaks.
VEVOR Marine Tank 14.53 gal
Capacity: 14.53 gallons. This tank features a visible gauge and a 9.8 ft (3 m) long hose. It has a two‑way vent cap and high‑density polyethylene construction to resist aging and impact. Best for boaters who need higher fuel capacity and a long hose for flexible placement. It recommends filling to 80% to minimize evaporation. Limitation: the hose length is fixed, so very tight spaces may require planning the installation path.
attwood 8806LPG2 6-Gallon Portable Tank
Capacity: 6 gallons. This tank uses automotive‑grade multi‑layer construction designed to withstand pressure in closed fuel systems and harsh environments. It includes an automatic vacuum valve for steady fuel flow without manual venting. Best for pontoons needing a compact backup or a lightweight primary option for short trips. Caution: smaller capacity means more frequent refueling on longer voyages.
Attwood 12 Gallon Portable Tank (8812LPG2)
Capacity: 12 gallons. This tank uses automotive‑grade multi‑layer construction and a built‑in automatic vacuum valve for consistent fuel flow. Designed for harsh environments and extended use, it suits pontoon boats requiring more fuel on longer trips. Best for boaters who value dependable fuel delivery and durability. Limitation: ensure compatibility with existing fuel fittings and space for a taller tank profile on deck.
Scepter 08669 Rectangular 12 Gallon Low Profile
Capacity: 12 gallons. This low‑profile version mirrors the popular 12‑gal design with a compact footprint, making it ideal for tight spaces or underslung mounting on pontoon boats. It includes a 2‑way vented cap and built‑in fuel gauge for quick checks. Best for boaters who need a thinner tank for limited deck height. Caution: verify exact dimensions to ensure a fit under seating or near rails.
Moeller Below Deck Permanent Fuel Tank (22-Gallon)
Capacity: 22 gallons. This permanent under‑deck tank offers a large capacity with a reinforced profile and corrosion‑resistant features. Best for pontoon setups where under‑deck storage is preferred and a long cruising range is needed. Limitation: installation is more involved and not suitable for quick swaps or temporary setups.
Buying Guide
Key purchase considerations help align a pontoon boat fuel tank with your typical usage and space. Consider capacity versus storage footprint, compatibility with your outboard engine, and whether you need a built‑in gauge or simple external indicators. Safety features such as vented caps to control vapor buildup and automatic vacuum valves for steady flow are valuable for longer trips. Material choice matters; high‑density polyethylene is common for durability, while metal tanks may offer different mounting options. If you operate in hot climates, choose tanks with UV resistance or adequate insulation to slow aging. Finally, plan for installation space, hose lengths, and fittings to ensure a clean, leak‑free setup.
How do I choose the right capacity?
Match capacity to your typical trip duration and average fuel burn. Pontoon boats often benefit from 12‑14 gallon tanks for a balance between weight and range. Use your engine’s fuel consumption rate to estimate how many hours of operation you want between refills. For long days on the water, a larger tank (like 14.53 gal) reduces the need for frequent refueling.
What about venting and fuel gauges?
A vented cap prevents dangerous vapor buildup during refueling, while a built‑in gauge or clear sight gauge saves time checking fuel levels. If you frequently refuel in windy or crowded conditions, a two‑way vented cap is especially helpful. For monitoring, tanks with a visible gauge let you plan ahead for fuel stops.
Are there compatibility considerations?
Ensure your new tank uses standard 1/4 NPT fittings or matches your boat’s existing fittings. Hose length and inlet/outlet positioning should work with your outboard or fuel line routing. Some tanks specify compatibility with ethanol blends or require careful use with particular fuels. For pontoons, verify mounting options and deck clearance before purchase.
What about installation effort?
Permanent tank installations require more time and space planning, especially for under‑deck models. Portable tanks are easier to swap between boats and store when not in use. If you plan to keep the setup simple, choose a portable tank with a built‑in gauge and a compact profile.
FAQs
- What capacity is best for a typical pontoon day cruise? A 12–14 gallon tank is a common balance between capacity and deck space, offering adequate range for a few hours without frequent refills.
- Is it safe to use diesel in a portable gas can? Some portable cans are designed to handle diesel, but always confirm fuel compatibility from the manufacturer before use to prevent damage or safety hazards.
- Do I need a gauge on my fuel tank? A built‑in gauge helps monitor fuel levels quickly and reduces guesswork, especially during family trips or fishing excursions.
- Can I mount a low‑profile tank on a pontoon? Yes, low‑profile tanks save space and fit better under seating or rail areas, but verify available clearance and mounting options on your craft.
- How important is venting in a marine fuel tank? Venting prevents buildup of vapor pressure during refueling and operation, reducing safety risks and ensuring steady fuel flow.
- Should I choose a portable or permanent tank? Portable tanks offer flexibility and easy transfer between boats; permanent tanks provide high capacity and a cleaner deck layout for long stays on the water.
