Scepter 9 Gallon Portable Marine Gas Can (08667)
The Scepter 9 Gallon Portable Boat Gas Tank provides ample capacity in a compact, space‑saving profile. It is suitable for small to mid‑sized boats and outboard engines that need longer running time. A built‑in fuel gauge helps monitor levels at a glance, and the 2‑way vented cap permits air flow during refueling while automatically relieving pressure to prevent vapor buildup. This tank is compatible with diesel and ethanol‑blended fuels, improving versatility. It accepts standard 1/4 NPT marine tank fittings and requires a separate fuel line for connections.
Best for: boaters who want a compact, easy‑to‑store tank with a built‑in gauge for quick checks. It’s a good match for boats that run shorter trips but need a reliable backup supply. Limitation: requires a separate fuel line and may not provide the extended capacity of larger tanks.

The design is suitable for boats where length and profile are constrained but more fuel is still desired. It’s best for boaters who want a bit more range without significantly increasing storage space. Caution: the larger capacity may be heavier to handle when full and requires appropriate mounting space.
Scepter 12 Gallon Portable Marine Gas Can, Tall Profile

It is best for boaters who need longer run times on outboard engines and can accommodate a taller tank in the storage area. It ensures a steady supply for weekend trips or longer excursions. Limitation: taller profile may require more vertical clearance and secure mounting in tighter compartments.

Buying Guide: Key Purchase Considerations
- Capacity needs: If you mainly cruise short distances, a 9–12 gallon tank may suffice. For longer trips, consider 14.5–14–plus gallons while ensuring storage space.
- Vent design and gauge: Vented caps help with refueling safety; built‑in gauges simplify fuel management on board.
- Fuel compatibility: Some tanks support diesel, ethanol blends, or gasoline only. Match to your engine and fuel type to prevent damage.
- Portability and mounting: Portable tanks should balance weight when full and fit your boat’s storage or deck area. Check mounting dimensions and strap points.
- Durability and material: HDPE is common for corrosion resistance and light weight; consider features like auto vacuum valves for steady flow.
- Hose and fittings: Some models include hoses or require separate fittings. Confirm compatibility with your engine’s fuel line and NPT fittings.
- Maintenance and safety: Ensure proper venting, secure caps, and avoid prolonged sun exposure to minimize evaporation and aging.
