Abstract: A fuel supply apparatus for a motor cycle allows the motor cycle to execute rapid jump traveling and accelerated drive just after the jump traveling. A fuel pump (P) and a fuel filter (F) connected to a pump suction path (Pa) of the fuel pump (P) are attached to a lid member (1) closing an opening portion (Ta) of a fuel tank (T). The fuel pump (P) provided with the fuel filter (F) is arranged so as to be inserted into the fuel tank (T) via the opening portion (Ta). The fuel filter (F) is arranged within a filter storage case (C) surrounding an entire outer periphery of the fuel filter (F) in an approximately sealed manner. A fuel supply hole (25) open to an inner side of the fuel tank (T) is pierced in a side wall (Cb1) along a gravity force direction (X) of the filter storage case (C).
