Understanding the Fuel System

Print

An automotive fuel system consists of everything between the fuel tank and the carburetor. This includes the tank itself, the fuel lines, one fuel filter, a mechanical fuel pump, and the carburetor.

With the exception of the carburetor, the fuel system is quite simple in operation. Fuel is drawn from the tank through the fuel line by the fuel pump, which forces it through the fuel filter to the carburetor, where it is distributed to the cylinders.
