Fuel supply system in Petrol engine

Here is the pump fuel supply system which is used in modern vehicles. In this pump fuel supply system.

The fuel tank stores the fuel and the Fuel pump sucks the fuel from the fuel tank and supply to the end of the engine. In between fuel passes through a fuel filter which purifies the fuel and then it transfers to the carburetor.

The carburetor mixes Petrol and air as per engine speed and load. Air comes to the carburetor through an air filter which cleans the air and transfers it to the carburetor. Then this fuel air mixture is transferred to the inlet manifold which transfers the carburized mixture to the engine through the inlet valve.
