What You'll Learn
Poly tanks are cheaper than steel or aluminium tanks
Poly tanks are a popular choice for fuel storage and transportation, especially for diesel fuel. They are often preferred over steel or aluminium tanks due to their cost-effectiveness and other advantages.
Poly tanks are generally cheaper than steel or aluminium tanks, making them a more economical option for many individuals and businesses. The price difference is significant, with new metal tanks costing around $1500-2500, while poly tanks can be purchased for free or at a much lower price. This affordability makes poly tanks accessible to those with limited budgets or those seeking a more cost-efficient solution for fuel storage.
One of the primary reasons for the cost-effectiveness of poly tanks is their durability and longevity. Poly tanks are known for their resistance to corrosion and rust, which are common issues with metal tanks. This means poly tanks can last for many years without the need for replacement, reducing long-term costs associated with fuel storage.
Additionally, poly tanks offer other benefits that contribute to their popularity. They do not spark, which is an important safety consideration when storing flammable fuels. Poly tanks are also lightweight and easy to handle, making them convenient for transportation and manoeuvring.
While poly tanks offer these advantages, it is important to consider potential drawbacks. Some users have reported issues with sunlight exposure, as prolonged exposure can cause the tanks to become brittle and crack over time. However, this can be mitigated by keeping the tanks covered or stored indoors. Additionally, it is recommended to keep poly tanks away from rodents, as they can chew through the material, leading to fuel leaks.
In conclusion, poly tanks are a more affordable option compared to steel or aluminium tanks, offering a durable and safe solution for fuel storage and transportation. Their resistance to corrosion and rust, coupled with their lightweight and non-sparking properties, make them a popular choice, particularly for those seeking a cost-effective and low-maintenance fuel storage solution.

They are chemical-resistant but not recommended for gasoline
Poly tanks are chemical-resistant and can be used for storing fuel. They are a popular choice because they are cheaper than steel tanks and do not corrode like aluminium tanks. However, they are not recommended for storing gasoline.
While poly tanks have been used for fuel storage for many years, there are some concerns about their safety when used with gasoline. Some people have reported that they can smell gasoline when a boat with poly tanks has been sitting for a while. This could indicate that the gasoline is permeating the tanks and could potentially lead to a dangerous situation.
One user reported that they had to replace their poly tank after a squirrel chewed a hole in it, which could be a potential hazard if the tank is storing gasoline. Another user reported that their farm tractors developed bacteria problems with black poly fuel tanks, causing slime to grow inside the tanks and plug the filters. This resulted in the engine stalling due to a lack of fuel.
Additionally, poly tanks can become brittle and crack over time, especially if they are exposed to direct sunlight. This could lead to fuel leaks, which could be dangerous if the fuel is gasoline.
Overall, while poly tanks may be suitable for storing some types of fuel, such as diesel, they are not recommended for gasoline due to safety concerns. It is important to carefully consider the potential risks before using poly tanks for fuel storage.

They are safer than metal tanks as they don't rust or corrode
Poly tanks are a popular choice for fuel storage, especially diesel, and are considered a safer option than metal tanks. One of the primary reasons for this is that, unlike metal, poly tanks do not rust or corrode. This is a significant advantage as it eliminates the possibility of rust or corrosion contaminating the fuel. Metal tanks are prone to rust and corrosion over time, which can lead to fuel contamination and affect the performance of engines.
Poly tanks are also favoured because they do not require welding during the manufacturing process, which means there are no slag or by-products from welding seams to worry about. This further reduces the risk of fuel contamination and ensures the integrity of the fuel stored inside.
In addition to being rust and corrosion-free, poly tanks offer other benefits. They are known to be more affordable than metal tanks, which can be a deciding factor for many. Poly tanks are also lightweight and easier to handle due to their lower weight and the inclusion of features such as hand grips. This makes them convenient for a range of applications, including agricultural and earthmoving equipment, where their portability is advantageous.
While poly tanks have proven to be a durable and reliable option for fuel storage, it is important to note that they are not without their vulnerabilities. Poly tanks should be kept out of direct sunlight as prolonged exposure can cause them to become brittle and crack over time. Additionally, while poly tanks are resistant to diesel, they may not be suitable for gasoline as it can be dangerous and cause the tanks to become brittle.

They are permeable and can be damaged by squirrels
Poly tanks are more permeable than steel or aluminium tanks. This means that, if left out in the elements, they can become brittle and crack. One user on Heavy Equipment Forums noted that their unused poly tank cracked in just a year and a half. Another user on the same forum shared that their poly tanks at work lasted 10 years before they had to be changed out, with the new tanks being kept covered with a tarp.
However, another user on the same forum noted that they have been using a poly tank in a trailer for years with no problems. They also observed that many agricultural and earthmoving equipment is fitted with poly fuel tanks, and that hundreds of thousands of poly water tanks have been installed in hot and dry climates without any issues.
Poly tanks are also susceptible to damage from squirrels. One user on Heavy Equipment Forums shared that a squirrel once chewed a hole in their John Deere tractor's poly fuel tank, which had to be replaced.
While poly tanks may be more permeable and susceptible to damage from squirrels, they do offer several advantages over metal tanks. For example, they are cheaper, do not rust or corrode, and do not have slag or biproducts from welding seams.
