Portable Marine Fuel Tanks Buyer’s Guide
When looking at portable marine fuel tanks, the basic things to consider are venting (for safety), size & shape, and portability. The type and size of your boat will likely help you determine some of these features.
Venting
With all of these tanks, swelling will occur. Newer regulations from the EPA have eliminated the traditional venting in portable boat gas tanks. All newer portable outboard boat fuel tanks won’t vent below 5 PSI and will have noticeable swelling. Many think that their tank or cap is defective because the fuel tanks will swell. However, this swelling is due to the fuel vapor building up pressure because the newly designed caps must stay sealed up to 5 PSI. In spite of this pressure and swelling, these new fuel tanks will remain safe and sealed even when swelling is visible.
Size & Shape
The size and shape of the tank of course are completely different in our examples. You will need to determine what size and shape will best suit your needs, based upon your boat size and capacity.
It is important that you take a minute and measure where you plan to put the tanks. Tanks come in low profile options or vertical options because of the various demands.
Portability
The portability of the tank is important as well if you plan on taking the tank on and off the boat. While some people do this, others fill up a gas can to fill the boat up.
If your preference is to move the tank on and off the boat, then you will certainly need to take into consideration how easy it is to handle. Is there an easy handle that will allow you to carry it with ease Does it have wheels so that you don’t have to manually carry it to the boat? These are good questions that you should be asking before making a final selection.
Conclusion
Portable marine fuel tanks should be chosen based on your motor’s consumption. You also need to take into consideration the area that you have available to put your tank on board your boat.
You also need to take into consideration how much you can lift or if you are going to leave the tank on board and bring the gas to it instead. Some fuel tanks have small wheels that will help you haul them to the water. If you have an outboard engine, most likely you have an external portable boat fuel tank.
You should also consider how much room you have on your boat and where you plan to store the fuel tank. The size of the motor and how much fuel consumption you might have.
We hope that you enjoy the options we have presented to you today. These options are some of the best portable marine fuel tanks that we found when doing our research and hope to save our readers from countless hours of research of their own.
