Scepter 08669 Rectangular 12 Gallon Low Profile Tank
The Scepter 08669 offers a 12-gallon capacity with overall dimensions of about 24.5″ L x 18.1″ W x 11.5″ H. It is built as a rugged one-piece shell designed to minimize fuel evaporation and preserve octane value during longer storage. Integrated molded handholds assist with transport, making it a practical option for boaters who prioritize handling ease and fuel efficiency.
Moeller 630013LP Low Profile 12 Gallon Tank
Moeller’s 630013LP uses seamless, thick-walled plastic and is noted for being up to 30% tougher than some competitors. The tank measures approximately 24.51″ L x 17.76″ W x 10.82″ H. It is designed for portable fuel transfer directly to the engine, not for permanent mounting. Replacement parts such as pickups, caps, and gauges are available, ensuring long-term usability.
Scepter 08667 9 Gallon Portable Marine Gas Can
The 9-gallon Scepter tank features a rugged one-piece tank shell that minimizes fuel evaporation and helps retain octane value during extended storage. It includes built-in handholds for easy transport and a built-in fuel gauge along with a two-way vented cap for safer refueling and pressure management. The unit is compatible with diesel and ethanol-blended fuels and is designed for outboard boats requiring reliable, portable fuel storage.
Moeller 620049LP Topside 6 Gallon Low-Profile Tank
Moeller’s 620049LP is a 6-gallon topside tank with a low profile, designed to be compact for tighter spaces. The paint-free, seamless, thick-walled plastic construction provides durability and resistance to impact. Like other portable Moeller tanks, it is intended for engine fueling transfers rather than a permanent installation, with replacements available for pickups, caps, and gauges.
Attwood 8812LLPG2 EPA Certified 12 Gallon Tank With Gauge
Attwood’s 8812LLPG2 offers EPA and CARB compliance with a built-in gauge. The tank is designed to save space by sitting 3 inches lower than typical 12-gallon models, making it a strong option for pontoon boats and others needing a lower profile while maintaining capacity. The multi-layer construction enhances safety and durability against pressure build-up in closed fuel systems.
Buying Guide: Key Considerations for Low-Profile Marine Fuel Tanks
- Capacity vs. footprint: Balance desired running time with available deck or topside space. Higher capacity often means a larger footprint, even in a low-profile design.
- Material and durability: Look for thick-walled, seamless plastics that resist cracking and evaporation. One-piece shells are common in high-quality tanks for better evaporation control.
- Ventilation and gauge options: Tanks with built-in gauges let you monitor fuel without guesswork. Vented caps help manage vapor buildup and safety during fueling.
- EPA and CARB compliance: For recreational boats, choosing EPA/CARB-certified options ensures adherence to fuel emission standards and broader regulatory compliance.
- Portability vs. permanence: Portable tanks are ideal for engines that require quick refueling or seasonal setup. For permanent installations, verify compatibility with mounting and fittings.
- Replacement parts: Availability of replacement pickups, caps, and gauges can extend the tank’s life and simplify maintenance.
- Compatibility with fuels: Ensure the tank material is compatible with gasoline, diesel, and ethanol blends as needed for your engine.
- Installation considerations: Check the model’s dimensions against your storage space and the mounting options on your boat to prevent interference with other equipment.
When evaluating options, compare the tank’s profile, gauge availability, and compatibility with your engine and fuel type. A low-profile design can improve balance and space on smaller vessels, while gauges and durable construction provide practical benefits for longer trips and frequent refueling.
