Carry fuel wherever your boating adventures lead with this 12-gallon/55L portable marine tank. Molded from high-density polyethylene, it resists aging, impact, and corrosion while holding its shape through years of use. A dual-function cap seals tight or vents with a simple turn of the yellow nut, promoting smooth fuel flow and reducing vapor leakage. The included 9.8 ft hose fits Yamaha-style connectors, making outboard setup quick on fishing boats, deck boats, or yachts. Bottom grooves ease transport and let the tank tuck neatly under boat seats, while a built-in fuel gauge keeps the level in clear view. Separate inlet and outlet ports help prevent spills and keep gasoline free of dirt and debris.
