The Best Marine Fuel Tanks for Boat Owners

Heading out to sea? Well, besides making sure your boat is fully stocked with all the necessary safety equipment, food, fishing rods, and so on, you’re going to want to make sure your fuel tank is full as well. If you really want to explore the water, you’ll need a sufficient amount of fuel, especially in case of emergencies. A marine fuel tank is a container that holds and supplies fuel to your motor. Here are some of the best portable fuel tanks for your boat.

Buying Fuel Tanks

Here are two very important factors to remember when shopping for the best fuel tank:

  • Size of the Boat: One of the main things you want to keep in mind is the size of your boat. If you have a large outboard engine, you should buy close to a 15- or 20-gallon fuel tank to support that. If your boat is much smaller and doesn’t burn that much fuel, then it makes sense to go with something like a 3-gallon fuel tank.
  • Fuel Capacity: Another important factor is the amount of fuel your motor is consuming on a regular basis. This coincides with the amount of space you have on the deck. If your boat is small and you don’t have much room, find a fuel tank that is slim and narrow, so it could be stored in small places like under your chair. Fuel tanks come in different shapes and sizes, so be sure to buy the proper one for you.

Now let’s take a look at the best marine fuel tanks!

Best Mini: attwood 3-Gallon Fuel Tank

The best 3-gallon fuel tank is from Attwood and is both EPA and CARB certified. Its automotive-grade, multi-layer construction can withstand pressure from build-up associated with closed fuel systems, and it’s capped with a built-in vacuum valve. This valve means no need for manual venting. It’s compatible with 1/4-inch NPT fuel fittings as well, and the shape is small and low to the ground, making it a perfect buy for small boat owners.
