Buying a Diesel Tank? Here’s How to Choose

Picking the wrong kind of tank could be dangerous, not just for your budget but also to yourself and the community. Using a tank that’s not suitable to your needs could post a fire hazard, and you could be liable for damages.

Here are the important things you need to consider when choosing a diesel tank to buy:


The style of the tank often determines what it is used for. For instance, the mobile diesel tanks you would see for sale at are prized for their portability, making them useful for onsite fueling. Rectangular tanks, on the other hand, offer the most capacity but have very limited application.


According to the American Society for Testing Materials, carbon structural steel tanks are adequate for most uses. Also, consider the tank’s coating. In most cases, rust-proof acrylic enamel is adequate, but if you require superior protection from harsh environmental elements, for example, go for an epoxy-based coat.


Keep in mind that most local codes require that you only fill up to 90% of your fuel tank’s maximum capacity. This will help you decide which tank will offer the best value. Also, tanks that can contain more than 35,000 gallons must be built on the site, as they can’t be transported from the factory to your site.


Insist on a tank built with thick material, that is 1/8-inch aluminum, 12-gauge steel, or 14-gague stainless steel. Also, make sure the tank you buy has been specifically pressure-tested. Lastly, inspect the appearance of the tank. You don’t want something that has chipping paint, dents, or scratches on the surface.

When buying a fuel tank, it’s best to identify your needs and restrictions. This helps you choose a tank that you know you won’t regret later. Also, check your local codes for storing flammable and combustible liquids, and be sure that the tank you choose adheres to this codes.
