It is not recommended to repurpose a fuel tank to store potable water due to the presence of leachable compounds
It is not recommended to repurpose a fuel tank to store potable water. This is mainly due to the presence of leachable compounds, which are contact toxins such as benzene and TCE at the PPM and PPB level, in the molecular grain structure of the base metal. These compounds can be difficult to remove and can pose health risks if they come into contact or are consumed by humans.
While it may be tempting to repurpose a fuel tank for water storage, especially given the versatility of tanks made from materials such as polyethylene, it is important to prioritize health and safety. Polyethylene tanks, for example, can be molded into various shapes and sizes and are superior to metal tanks in many ways, including their resistance to rust, corrosion, and degradation. They are also cheaper than most other materials. However, not all polyethylene tanks are created equal, and different grades and densities must be considered, especially if storing corrosive materials.
In the case of fuel tanks, the type of fuel previously stored and the grade of plastic used are important factors to consider. For example, diesel fuel requires a tank with a diesel-resistant gel coat or epoxy barrier coat, while water tanks require a potable water coating. Using a tank that does not meet these specifications can lead to issues such as liquid finding its way through voids in the material.
Additionally, there may be chemicals or rust residues in metal fuel tanks that can leach into the water, rendering it unsafe for consumption. This is supported by a user on Expedition Portal, who advised staying away from metal toolboxes or fuel cans for drinking water due to the presence of unhealthy chemicals and the potential for leftover fuel and rust to contaminate the water.
In summary, while it may be tempting to repurpose a fuel tank for potable water storage, it is not recommended due to the potential presence of leachable compounds and other contaminants. It is crucial to prioritize the safety and health of those who will be consuming the water, and alternative options, such as purchasing purpose-built plastic water storage containers, should be considered instead.

Polyethylene tanks are versatile and can be moulded into various shapes and sizes, but different grades have varying chemical and heat resistance
While a fuel tank can be repurposed to store water, it is not advisable to use it for potable water. This is because it is difficult to remove leachable compounds (contact toxins such as benzene and TCE) from the molecular grain structure of the base metal.
Polyethylene tanks are a popular choice for storing water, fuel, chemicals, or cooking grease. This is because polyethylene is a malleable material that can be moulded into various shapes and sizes. It is also lightweight, cost-effective, and highly resistant to corrosion and chemicals. However, it is important to note that different grades of polyethylene have varying chemical and heat resistance. For example, while polyethylene can handle cold temperatures and stay intact at lower temperatures than polypropylene, it is not suitable for constant high-temperature applications above 100°F. Additionally, polyethylene has lower abrasion resistance and cannot resist as wide an array of organic solvents, chemicals, and acids as polypropylene.
Polyethylene tanks are highly versatile and can be customised to meet specific industrial requirements. They are also superior to metal tanks as they do not rust, corrode, or degrade, and they are cheaper and lighter. However, one limitation of polyethylene tanks is that they cannot be welded, which can make repairs more challenging.
When choosing between polyethylene and other materials such as stainless steel or polypropylene, it is essential to consider factors such as chemical compatibility, durability, weight, temperature resistance, and cost.
