PROBLEM TO BE SOLVED: To prevent the occurrence of a fuel deficiency phenomenon when fuel flows backward when a vehicle climbs and travels on a slope in a fuel feeding device including a fuel injection pump. SOLUTION: This fuel feeding device has a fuel tank 10 (or a sub-tank 10'), a fuel filter 20 arranged lower than the fuel tank (or the sub-tank), the fuel injection pump 30 for sucking, forcibly feeding and injecting the fuel, fuel feeding passages 40 and 50 communicating up to the fuel injection pump via the fuel filter from the fuel tank, and an air bleeding passage 60. The fuel feeding passage 40 and the air bleeding passage 60 are arranged for forming the crest-shaped apexes 41 and 63 functioning as an air vent capable of contacting the fuel with air so that the fuel is always filled over an upstream side prescribed area from a fuel introducing port 31a of the fuel injection pump 30 regardless of an inclined state of the vehicle in driving. Thus, even in slope climbing travel, a backflow of the fuel is prevented, and stable travel can be performed. COPYRIGHT: (C)2005,JPO&NCIPI
