PROBLEM TO BE SOLVED: To provide a compact fuel supply device reduced in the number of components while keeping high performance.SOLUTION: A fuel supply device 1 includes a pump body 3, and a partitioning wall 17 and a sectioning wall 18 respectively partitioning the inside of the pump body 3 into a pump chamber 13, and a part 4a and the other part 4b of a fuel inflow chamber 4. A fuel pump 8 in the pump chamber 13 includes a vent hole 8a for discharging air bubbles inside to the pump chamber 13. The partitioning wall 17 includes a peripheral wall 17a on its peripheral edge portion. A fitting portion 13a to which the peripheral wall 17a is fitted through an O-ring 23, is disposed on an inner wall of the pump chamber 13. A strainer 10 connected to the fuel pump 8 by a connection passage 9 is extended to the other part 4b of the fuel inflow chamber 4. The connection passage 9 and the partitioning wall 17 are formed of a single component. |
