PROBLEM TO BE SOLVED: To reduce pressure loss of a fuel by reducing the total size of a fuel feeder to realize a compact and lightweight fuel feeder, and providing a simple piping by considering a place of arranging a filter. SOLUTION: In a fuel feeder comprising a suction filter, a fuel pump connected to the suction filter by a connection pipe to discharge the fuel passing through the suction filter, a fuel passage protruded from an upper part of the fuel pump, and a one-way directional valve disposed on an inlet part of the fuel passage, a high-pressure filter is disposed in the fuel passage on the downstream side of the one-way directional valve, and the dust in the fuel is removed by the suction filter and the high-pressure filter in the fuel passage.
