Abstract: PROBLEM TO BE SOLVED: To provide a fuel-feeding system for cooling a pump controller and miniaturizing a canister. SOLUTION: A fuel pump 20 is housed in a fuel tank 10. The pump controller 30 feeds power to a pump body 22 according to engine operation state, so that the pump body 22 of the fuel pump discharges a fuel quantity necessary for the engine and controls the rotational frequency of the pump body 22. The canister 40 adsorbs vaporized fuel inside the fuel tank 10 by activated carbon housed in its interior. Piping 105 is connected to the canister 40, to introduce the atmosphere inside the canister 40. When a solenoid valve 106 is opened, the atmosphere is introduced inside the canister 40 from the piping 105. Since the piping 105 is in contact with the pump controller 30, the atmosphere introduced to the canister 40 by the piping 105 is heated by the pump controller 30 and the temperature of the canister 40 is increased by introducing the heated atmosphere.

Abstract: PROBLEM TO BE SOLVED: To provide a suction filter which retains a liquid film to thereby filter fuel satisfactorily regardless of a liquid level position of the fuel within a fuel tank and decreases air contained in the fuel sucked into a fuel pump, and a fuel supply device using the suction filter.
SOLUTION: The suction filter 20 includes a liquid film formation section 22 in the vicinity of a suction port 12 of the fuel pump 11 in a filter body 21. The fuel the foreign matters of which have been removed by passing through the filter body 21 is sucked into the fuel pump 11 via the liquid film formed at the liquid film formation section 22 in the vicinity of the suction port 12 of the fuel pump 11. Thus, the fuel sucked into the fuel pump 11 passes through the liquid film formed at the liquid film formation section 22. Therefore, even if part of the suction filter 20 is exposed from the fuel to the air due to the liquid level position within the fuel tank 1, air contained in the fuel sucked into the fuel pump 11 is decreased.

Abstract: PROBLEM TO BE SOLVED: To provide a fuel filter combining the assurance of filtering performance and the extension of a service life with simple adjustment.
SOLUTION: Fuel passing through the fuel filter 30 flows from the outside to the inside of a filter body 31. The filter body 31 has an outer peripheral layer part formed of nonwoven fabric, and an inner peripheral layer part formed of filter paper. Comparatively large ones out of foreign matters included in the fuel are thereby captured in the outer peripheral layer part, and comparatively small ones are captured in the inner peripheral layer part. Consequently, clogging of the filter paper in the inner peripheral layer part is reduced. The desired filtering performance can easily be set by selecting the nonwoven fabric and filter paper. The assurance of filtering performance and the extension of the service life with simple adjustment can be combined. The outer edge of the filter body 31 is sealed with a molding part 32. A mounting part 50 for mounting a sub-tank 11 is installed at the molding part 32. Since the mounting part 50 is formed integrally with the molding part 32 at the same time, the number of parts is reduced.

Abstract: PROBLEM TO BE SOLVED: To provide a fuel filter formable into an optional shape and a fuel supplying device using the fuel filter. SOLUTION: This fuel filter 40 is arranged on the fuel inflow side of a pump main body to surround the outer periphery of the pump main body. The cylinder part 43 of a core member 41 is mainly constituted of fine resinous materials extended in the axial direction and fuel is made to pass through gaps formed between the adjacent resinous materials. A filter main body 50 has an inner peripheral filter layer 51 formed on the inner peripheral side close to the part 43 of the body 50 and an outer peripheral filter layer 52 formed on the outer peripheral side of the layer 51. The layer 51 is denser than the layer 52. The filter 40 is obtained by immersing the member 41 in the aqueous solution where a fibrous material having the composition of the layers 51 and 52 is dissolved and forming the layer 51 and the layer 52 in this order while sucking the aqueous solution.
