Where is the fuel pump in 18 wheeler?
In an 18-wheeler, the fuel pump is typically located inside the fuel tank. The fuel tank is usually mounted on the side of the frame, either behind the cab or between the axles. The fuel pump is responsible for drawing fuel from the tank and delivering it to the engine. It is powered by an electric motor and is controlled by the engine control unit (ECU). The ECU monitors the fuel level and controls the fuel pump to ensure that the engine receives the correct amount of fuel. The fuel pump is also equipped with a filter to remove any contaminants from the fuel.
