attwood 6-Gallon Portable Marine Fuel Tank with Gauge — EPA & CARB Certified, Low-Permeation Multi-Layer Construction

Attwood's 6-gallon portable marine fuel tank is an EPA-certified, CARB-approved fuel system that adapts to virtually any outboard engine and includes an easy-to-read fuel gauge.

Built for boaters who need a reliable, compliant fuel source, this tank combines automotive-grade multi-layer construction with low-permeation technology and an automatic vacuum valve to deliver steady fuel flow and minimize evaporation. Attwood engineered this solution to meet EPA, CARB, and ABYC standards so you can use a portable tank that’s tested for marine conditions without sacrificing compatibility or convenience.

How does this tank keep fuel flow steady during use?

The tank features an automatic vacuum valve that regulates internal pressure so fuel flows consistently to the outboard without manual venting. That valve works with the tank’s closed system design to prevent surges and air locks, improving engine run time and reliability.

• Automatic vacuum valve for continuous fuel delivery
• Closed-system design reduces air ingestion and interruptions
• Compatible with standard 1/4" NPT fittings for straightforward hookup

What makes this portable tank durable enough for marine use?

Attwood uses a proven multi-layer, automotive-grade construction that resists pressure, impacts, and the thermal shifts found in harsh marine environments. The materials and assembly are chosen to withstand heavy use while keeping structural integrity and safe containment of fuel.

• Multi-layer construction resists pressure and wear
• Designed to tolerate temperature swings and rough handling
• Tested to ABYC standards for marine durability and safety

Does this tank prevent fuel loss and meet emissions rules?

Yes — low-permeation materials reduce fuel evaporation and vapor loss, helping you conserve fuel and comply with emissions regulations. The tank is certified by the EPA and CARB so it meets the regulatory requirements for portable marine fuel containers.

• Low-permeation technology minimizes evaporation
• EPA certified and CARB approved for regulatory compliance
• Designed to meet ABYC guidelines for portable tanks

How easy is it to install and use with different outboard engines?

The tank adapts to virtually any outboard engine and accepts standard 1/4" NPT fittings for fast, reliable connections. A built-in fuel gauge gives a quick visual of remaining capacity, and the compact 6-gallon size balances usable range with convenient handling and storage.

• Works with common 1/4" NPT fittings for simple installation
• Integrated fuel gauge for quick level checks
• 6-gallon capacity offers a balance of range and portability
