A fuel tank with a pump typically consists of several main components, which work together to ensure the proper supply of fuel to the engine.
- Fuel Tank Body: It is the main container for storing fuel. Usually made of metal or high - strength plastic, it is designed to have a certain capacity to meet the fuel consumption needs of the vehicle or equipment. The tank body is equipped with various connections and fittings, such as inlet and outlet pipes, vent pipes, and mounting brackets.
- Fuel Pump: The fuel pump is a crucial component. It is usually located inside the fuel tank or at the tank outlet. Its function is to draw fuel from the tank and deliver it to the engine's fuel system under a certain pressure. There are different types of fuel pumps, such as electric fuel pumps and mechanical fuel pumps. Electric fuel pumps are more commonly used nowadays, which are driven by electricity and can provide a more stable fuel supply.
- Fuel Filter: The fuel filter is installed in the fuel line, usually between the fuel tank and the engine. Its main function is to filter out impurities, dirt, and water in the fuel to prevent them from entering the engine and causing wear and damage to engine components. A clean fuel filter is essential for the normal operation of the engine.

Fuel Level Sensor: The fuel level sensor is used to monitor the fuel level in the fuel tank. It is usually installed inside the tank and works by detecting the height of the fuel surface. The sensor sends the fuel level information to the vehicle's instrument panel, allowing the driver to know the remaining fuel quantity at any time.
