Understanding the Fuel System

Print

An automotive fuel system consists of everything between the fuel tank and the carburetor or fuel injection unit. This includes the tank itself, all the lines, one or more fuel filters, a fuel pump (mechanical or electric), and the carburetor or fuel injection unit.

With the exception of the carburetor or fuel injection unit, 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 to the fuel filter, and from there to the carburetor where it is distributed to the cylinders.
