Fuel trucks encompass a range of vehicles dedicated to transporting different types of fuels, from gasoline and diesel to biofuels and heating oil. These trucks are designed with robust fuel - storage tanks, typically made of steel or stainless steel, to ensure durability and safety during transit. They are equipped with reliable pumping mechanisms for efficient fuel transfer and accurate metering devices to measure the quantity of fuel being transported. Safety features, including double - walled tanks, emergency shut - off valves, and spill - containment systems, are standard to prevent leaks and mitigate risks associated with flammable fuels. Fuel trucks serve as essential links in the fuel - distribution chain, ensuring that fuel reaches gas stations, industrial sites, and other consumers in a timely and secure manner.
