The Attwood Portable Fuel Tank is a 12 gallon boat gas tank built for boaters who need dependable auxiliary fuel without a permanent installation. Carrying a full 12 gallons of fuel plus a 0.75-gallon allowance for two-cycle oil at a 1:16 mix, it suits pontoon boats, small outboards, and tiller-steered rigs that burn through fuel on longer runs. A built-in, high-contrast gauge lets you read the level at a glance instead of guessing. For anyone tired of cutting trips short over fuel anxiety, this tank from Attwood Marine adds real range. See our full lineup of marine fuel systems for matched hose and fitting options.
Construction is where this 12 gallon boat fuel tank earns its keep. The shell uses a multi-layer co-extruded polyethylene with an ethylene vinyl alcohol barrier layer, the same low-permeation approach used in automotive fuel systems, which keeps evaporative losses under 1 kPa restriction at 50 liters per hour. The tank accepts standard 1/4-inch pipe-thread fuel fittings and runs ethanol-blended fuels without trouble. A ratcheting cap with a tether and an automatic vacuum valve with a high-flow design round out the top. Every unit is leak-tested at the factory and certified to federal and California emissions standards, meeting the marine industry requirements for portable tanks. The body is also resistant to sun and ozone exposure on open decks.
Pair this tank with a tiller outboard, a kicker motor, or a pontoon main engine when you want more time on the water between fill-ups. Measuring 22.75 inches long by 14.25 inches wide by 14.47 inches tall, it stows in most under-seat lockers or against a transom bulkhead, and the molded handle makes carrying it to the dock manageable at under nine pounds empty. Attwood backs it with a two-year warranty. If you're outfitting a tiller setup, check our engine controls and add a backup gauge while you're building out the helm.
It holds a full 12 gallons of gasoline, with an additional 0.75-gallon allowance for two-cycle oil when running a 1:16 fuel-to-oil mix. That capacity makes it a strong match for pontoon boats and small outboards that need more range between fill-ups.
