One primary selling point of this Moeller fuel tank is its visible cap. It makes it easy to estimate the fuel level by being more of a fuel gauge. This proves to be helpful to avoid running out of gas before setting sail for a boating experience.
The tank then includes a vent through which it releases any pressure building up inside the caddy. By doing so, it promotes the gas tank’s proper functionality. Besides the varying capacities, you can also get the tank in white or red. And as much as the color isn’t a significant feature, it could add some style to your boat’s structure.

Scepter USA 6792 Duramax Flo-N-Go Fuel Caddy: Best Rolling Gas Tank
If high capacity and durability are what you are looking for, the Scepter Duramax Flo’ n’ Go delivers just that. Relative to its capacity and features, the Scepter Duramax gas tank is relatively cheap.
It boasts a high capacity of 14-gallons which translates to more boat running time. Helping its functionality are several functional valves and seals alongside a pump. The tank’s construction then features high-density propylene. As such, it’s not only resistant to dents but also dust and corrosion, making it suitable for marine, rural, and farm use.
With such a capacity and shape, you can tell that it’s not the most portable gas tank. To address this, the Scepter included two sturdy wheels, which make its transportation pretty easy. At the top of this heavy-duty caddy is a fitted handle. You can use this to wheel or carry it around.
Given the wheel provision, you’ll have to store this gas tank in an upright position in most cases. This will also facilitate the proper use of its pump in starting, restarting, and stopping the gas. The pump is automatic and will therefore help control how much gas flows into the engine.
Even so, the pump may sometimes have operating issues, which may be a result of airlocks. Be sure to rime before using it to handle such situations. It’s also an eco-friendly boat gas tank, thanks to the self-vents. They open to contain any pent-up pressures, thus preventing pollution.
On the downside, completely draining this gas tank is quite a hassle due to the tank bottom’s design. To drain any remaining fuel, you’ll need to flip the caddy upside down.
- Two sturdy wheels for effortless transportation
- 14-gallon large capacity
- Self-vents which make it eco-friendly
- An auto-pump to control the flow of gas
- Durable and sturdy construction
- Quite tricky to completely drain the unit

It then features a multi-layer, automotive-grade construction. Such a design can effectively withstand any pressure build-up that tends to arise from expanding gas.
However, the tank itself is non-vented. That’s why to address this; you’ll need to install a ¼-inch NPT fuel fitting. The tank’s cap incorporates a vacuum valve, promoting self-venting, especially when too much pressure is inside the tank.
In terms of safety, this Attwood gas tank satisfies both the NMMA and ABYC regulations. Therefore, safety is something you won’t have to fret about when using this gas caddy. It also features a built-in fuel gauge to aid in approximating the fuel level.
The tank uses sturdy plastic for its construction. So, if a durable boat gas tank with excellent functionality is what you are after, this unit from Attwood is undoubtedly a solid choice.

Additionally, this unit brags a stainless-steel, rugged construction. This assures not only resistance to various elements but also durability to boot. So, if PET plastic isn’t your type of material, this gas tank may suit you best.

As part of the package, the unit features a replaceable anti-slosh foam. In other words, it minimizes leakages or sloshing when the waters get rough or in case your boat is subjected to shock waves.
When it comes to the tank’s design as well, the Stark Universal gas tank is exceptional. Instead of using plastic like most fuel caddies, it boasts a top-quality polished aluminum construction. And other than the elegant design, it’s also highly instrumental in protecting the gas within.

Buying Guide for The Best Gallon Boat Gas Tanks
Gas is potentially hazardous by nature. Therefore, it’s principal that boat gas tanks satisfy the industry safety standards and requirements. There are two major governing bodies with authority to regulate this type of product: The National Marine Manufacturers Association (NMMA) and the American Boat and Yacht Council (ABYC).
Your fuel tank needs to have NMMA type fuel system certification in terms of performance, installation, and design. By ensuring so, you are assured of enjoyable and safe boating adventures.
Most fuel tanks have their capacity ranging from as low as 3 gallons up to 35 gallons. The more the capacity, the heavier the gas tank. Remember, you’ll have to unmount and load the tank regularly on your boat, so you should consider one that’s quite effortless to carry.
A gas tank with a bigger capacity also translates to more running time. However, there’s a high chance you need a gas tank for a relatively small boat that hardly uses much fuel. Consider an option whose capacity strikes a reasonable balance between running time and portability.
Again, gas is highly hazardous. Therefore, when designing gas tanks, all manufacturers consider safety with the utmost significance. Keep in mind that gas tends to expand when subjected to hot temperatures.
Hence, we would advise that you only fill the tank’s capacity up to 90% to provide room for expansion and prevent spills. Having gas filled up all the way may damage the unit. To cover for any safety concerns, you must:
- Offload the tank when it’s not needed to reduce the risk of accidents.
- Pick a tank that features vents on the side to facilitate pressure release
- Consider using fuel that doesn’t include ethanol. The reason being, ethanol tends to sink with time and may damage the bottom of the tank.
Size and Shape
You’ll also need to consider the gas tank’s size and shape. In other words, ensure the gas tank you pick fits in your boat with zero limitations. You need to check and counter-check your requirements to ensure you end up with the right tank. If your boat only holds 3 gallons of gas and has limited storage space, you can’t go buying a 12-gallon boat gas tank.
Also, understanding your engine’s consumption is vital to help you identify the correct size. If your boat consumes minimal gas, opt for a reasonable size. Understanding this will help utilize your boat’s space to avoid running out of room for other trip necessities.
Take a moment and measure the space you wish to put in your gas tank. By doing so, you’ll have a much better insight into the most appropriate gas tank shape as well.
There’s a high chance you’ll sometimes have to take the gas tank on and off your vessel. As such, the tank’s portability is worth consideration. You’ll also need to consider how effortless it is to handle the tank.
Does it include a handle to facilitate easy carrying of the unit? Are there wheels that save you the trouble of manually carrying the tank to the boat? These are ideal questions to ask if a typical portable boat gas tank is what you wish for.
While some people consider gas tank portability to be a significant concern, others don’t. Instead, they fill up smaller gas cans and use them to fill up the gas tank. At this point, the portability of the tank is a matter of individual preference.
