Claims

[Scope of utility model registration request]

The fuel pump built into the fuel tank is connected to one end of the fuel pipe that passes through the tank container of the fuel tank and communicates with the engine, and a fuel filter is formed at the fuel suction port of this fuel pump. In a fuel filter in which the filter case that forms the outer shell of the fuel filter is formed of a wire mesh or a resin mesh, the filter case must be loaded with filter paper or a sponge-like fiber filter material. A fuel filtration device for a fuel tank featuring:
