The fuel system of the Volkswagen begins at the front of the automobile, where the fuel tank is situated behind the spare tire. On type 2 vehicles, the tank is at the rear, ahead of the engine. From the tank the fuel is drawn through fuel lines to the mechanically-operated fuel pump located on the crankcase of the engine. From the pump, fuel goes to either a single down-draft Solex carburetor (type 1 and 2) or to a pair of Solex down-draft carburetors (type 3).

Since 1968, the type 3 has used an electronic fuel injection system. This system is discussed at the end of this section.
