Our verdict
The Moeller Marine Portable Fuel Tank is a reliable, budget-friendly choice for boaters needing extra fuel capacity or a replacement tank. Its tough polyethylene construction, EPA-compliant venting, and range of sizes make it a practical option for small to mid-sized boats, though buyers should budget separately for connector hoses and expect average performance from the built-in gauge.

Full review
The Moeller Marine portable fuel tank is a purpose-built solution for boaters who need reliable, mobile fuel storage without the permanence of an inboard system. Constructed from translucent, UV-stabilized polyethylene, the tank allows users to visually monitor fuel levels at a glance, eliminating the guesswork that comes with opaque containers. Available in a range of capacities, from compact six-gallon models suited for small outboards to larger twelve-gallon tanks for extended trips, it accommodates everything from tenders and jon boats to larger recreational vessels needing an auxiliary supply. The low-profile, space-efficient design fits neatly into tight hull compartments or storage lockers, making it a practical choice for anglers, weekend cruisers, and marine professionals alike.
Built with boater safety and EPA/CARB compliance in mind, the Moeller tank features a vented cap system that manages pressure buildup while minimizing fuel vapor emissions, aligning with modern environmental regulations for marine fuel storage. The fuel line connects via a corrosion-resistant fitting designed to work seamlessly with Moeller’s primer bulbs and quick-connect hardware, ensuring a secure, leak-free link between tank and engine. Reinforced handles on either side make transport and refueling straightforward, even when the tank is full, while the tank’s squared-off base provides stability on deck or dock surfaces, reducing the risk of tipping during rough handling or choppy conditions.
Durability is central to the tank’s design, with a thick-walled construction that resists cracking, UV degradation, and the corrosive effects of saltwater exposure over repeated seasons of use. The fuel gauge, integrated directly into the cap assembly on select models, offers an added layer of convenience for boaters who want a quick visual check without removing the tank from its mounting location. Whether used as a primary fuel source for small craft or as a backup reserve for longer voyages, the Moeller Marine portable fuel tank delivers the dependable performance boaters expect, backed by a reputation built on decades of manufacturing marine fuel systems and accessories trusted across the industry.
