Abstract
A fuel feed apparatus is accommodated in a fuel tank. Hooking projection parts have claws formed on a fuel discharge side of a fuel pump. The claws are fitted and hooked in an opening formed on a filter case, so that the fuel pump is protected from dropping out from the filter case. The entire circumference of the fuel discharge side of the fuel pump is inserted with force into a press-insertion part formed in the filter case. A fuel suction side of the fuel pump is not supported by other parts, so it is in free condition.
