Function of fuel pump
The fuel pump in a vehicle has the central task of supplying the engine with the required fuel. It is often located in the fuel tank and ensures constant pressure in the fuel lines to guarantee optimum combustion.
The required pressure can vary depending on the vehicle and engine type. The fuel pump is usually operated electrically and controlled by the engine control unit. Modern fuel pumps are designed to adapt to the current driving conditions to ensure optimum fuel efficiency.
