HGV Fuel tanks are large containers that are used to store fuel in heavy goods vehicles (HGV). They are typically made of metal, such as steel or aluminum, and are designed to withstand the rough conditions that HGV's are subjected to. They are typically located under the vehicle and designed to hold large amounts of fuel, ranging in capacity from around 100 to several hundred gallons. They are also designed to prevent fuel leaks and spills and to minimize the risk of fire. They are usually made of steel or aluminum, and are coated to prevent rust and corrosion. Many fuel tanks are also equipped with anti-siphon devices to prevent fuel from being siphoned out of the tank. It's important to regularly check and maintain your fuel tank, as a damaged or leaking fuel tank can cause fuel spills and potential fire hazard.
