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

Attwood's 6 gallon portable marine fuel tank delivers a certified, low‑permeation fuel storage solution that adapts to nearly any outboard engine while including a built‑in gauge for easy monitoring.

Built with automotive‑grade multi‑layer construction and engineered for marine environments, this portable tank is EPA certified, CARB approved, and designed to meet ABYC standards. Its durable materials, automatic vacuum valve, and standard 1/4" NPT compatibility make it a reliable option for trailering, tender boats, or as a convenient reserve tank. Attwood combines long experience in marine systems with tested safety features so boaters get a ready‑to‑connect fueling option that minimizes evaporation and simplifies installation.

How does this tank prevent fuel loss and evaporation?

The tank uses low‑permeation materials and multi‑layer construction to reduce fuel vapor escape and maintain fuel quality over time. This is especially useful for storage periods and in warm conditions where ordinary containers can lose volume to evaporation.

• Low‑permeation inner layers limit hydrocarbon escape.
• Multi‑layer construction resists pressure changes in closed systems.
• Certified manufacturing meets EPA and CARB standards for emissions control.

Will it work with my outboard engine and how easy is it to install?

The Attwood tank adapts to virtually any outboard thanks to standard 1/4" NPT fittings and a vacuum‑automated vent system that supports consistent fuel flow without manual venting. Installation is straightforward for anyone familiar with portable fuel lines and fittings, and the included gauge gives immediate fuel level feedback.

• Compatible with common 1/4" NPT marine fuel fittings and hoses.
• Automatic vacuum valve maintains steady delivery to the engine.
• Top-mounted gauge shows remaining capacity at a glance for easy refueling planning.

How durable is the tank in harsh marine conditions?

Designed to survive temperature swings, UV exposure, vibration, and frequent handling, the tank employs automotive‑grade materials chosen for toughness and long service life. Its construction maintains structural integrity when used as a portable tank on trailers, tenders, or larger boats where movement and impacts may occur.

• Automotive‑grade outer layers resist abrasion and puncture.
• Engineered to handle pressure and repeated use in closed systems.
• Tested for compliance with ABYC standards for portable marine tanks.

What safety and compliance features should I expect?

This model is EPA certified and CARB approved, reflecting manufacturing controls that limit emissions and meet regulatory testing. Features such as the automatic vacuum valve and low‑permeation construction support safer, cleaner operation compared with non‑certified portable containers.

• EPA certification and CARB approval for reduced evaporative emissions.
• Automatic vacuum valve for stable fuel delivery and sealed venting behavior.
• Meets ABYC guidelines for portable fuel tanks used in recreational vessels.

Who is this for? The Attwood 6 Gallon Portable Marine Fuel Tank is aimed at recreational boaters, anglers, and tender operators who need a dependable, portable fueling option that complies with current emissions standards. It suits owners who value straightforward installation, measurable fuel levels via a built‑in gauge, and materials engineered to withstand real‑world marine wear and temperature variation. Choose this tank when you want a certified, trail‑ready fuel solution that balances convenience with regulatory compliance and durability.
