Abstract
A fuel filter device includes a bag-shaped filter member and is adapted to be attached to communicate an inner space of the filter member with a fuel suction opening in a fuel tank. The filter member is configured in a multilayer structure. At least one layer of the filter member is configured to serve as an inhibition layer having a structure to prevent water in a fuel tank form coming into the inner space of the filter member by a pressure applied to the filter member when the water is frozen.
