A fuel supply system for a vehicle is provided with a fuel pump disposed in a fuel tank sitting astride a vehicle body frame. The fuel pump is disposed along a side surface of the fuel tank in a position opposed to a portion of the vehicle body frame. This fuel supply system for a vehicle provides a system in which a fuel pump can be disposed even in a fuel tank of a saddle-ridden vehicle with minimum modifications required in size and shape.

An air cleaner for use in combination with a fuel system of an engine, includes an air cleaning element housed within a casing. Air introduced from an air inlet, defined in the casing, follows an air flow path from the air inlet passing through the air cleaning element. The air flow path includes a direction change of approximately ninety degrees. This direction change transpires over a curved guide surface formed in the casing to reduce the likelihood of vortexes which reduce the air ram pressure. The curved guide surface may include a detachable panel. Also, the panel may include an air path to an air branch chamber. When two air inlets are used, it is advantageous to include a partitioning wall separating the two air flow paths prior to the air cleaning element.

A fuel carbureted in a float chamber of a carburetor is prevented from entering through an air vent path into an air intake path during low velocity running of a vehicle. An outer vent path and an inner vent path are provided on the upstream side of an air vent path which communicates with a float chamber of a carburetor of an engine for a vehicle. The paths are alternatively selected by a solenoid valve. An opening of the inner vent path is opened in the intake duct, and an opening of the outer vent path is opened at a position sufficiently spaced away from the front face air intake. During low velocity running, the solenoid valve is selectively operated so that the outer vent path is in communication with the carburetor. During high velocity running, however, the inner vent path is in communication with the carburetor.
