If you have an older boat, chances are that the tank is made from fiberglass or stainless steel, but these had numerous problems, so many boat manufacturers began using plastic and aluminum. The plastic and aluminum tanks are durable, but the problem is that they are not all compatible with diesel fuel. For this reason, many people have turned to using aluminum fuel tanks on their boats, which serves quite a few advantages, but there are also a few disadvantages to using an aluminum fuel tank.
Aluminum Marine Fuel Tanks
When looking at aluminum marine fuel tanks, you will find that they have a few advantages and a few disadvantages. One of the advantages is that the aluminum material is much lighter than plastic, fiberglass or stainless steel. This will allow the boat to weigh slightly less, which will allow you to achieve better fuel economy. In addition, the lighter weight will make it substantially easier for you to install the tank if you want to do it yourself.
In addition, aluminum is an extremely durable material, which is nearly impossible to crack; whereas, plastic might crack under lesser circumstances. One disadvantage with aluminum fuel tanks is that some people claim that they will corrode easier than other materials, but this is not necessarily true. Aluminum will not corrode simply from making repetitive contact with water, but it may corrode if water somehow becomes trapped between a foreign object and the tank for extended periods of time.
Spun Aluminum Fuel Tanks
If you want to have a unique looking fuel tank, you may want to consider spun aluminum fuel tanks. Spinning aluminum is simply a way for the aluminum to be formed and bent into a cylinder like shape instead of the traditional rectangular style. A lot of people really like spun aluminum fuel tanks because of the unique style and design. The only real disadvantage with spun aluminum is that if it is damaged or dented, it will be cheaper to replace it than to repair it, and they are not very cheap to replace.
Aluminum Fuel Tanks for Boats
You will find that aluminum fuel tanks for boats come in a wide variety of shapes, styles and designs. You will also find that aluminum will be a little more durable than plastic, and it will definitely give your boat a slightly better appearance and better fuel economy. The prices will widely vary depending upon which style and design you choose, but you should be able to stay under $500.
If you are looking to replace the fuel tank on your boat, you now know that aluminum is a very good choice. Aluminum will give your boat a better appearance, better fuel mileage and the tank will be more durable. The only thing you need to watch out for is to ensure that water does not become trapped between an object and the tank because this can lead to corrosion.
