PROBLEM TO BE SOLVED: To provide a fuel supply device in which an enclosure wall for enclosing a filter and a snap-fit mechanism for connecting first and second housings are arranged while being separated from each other in the axial direction, resulting in a reduction in the diameter.SOLUTION: The fuel supply device includes a first housing 1 which includes a base part (7) having a mounting flange (6), a pump holding wall (8) rising therefrom, and an enclosure wall (10) rising from the inner peripheral edge of the flange (6) while enclosing the pump holding wall (8), to define a fuel storage part (9), and a second housing (2) which is connected to the first housing (1) via a snap-fit mechanism (55) for holding a fuel pump (4) in cooperation with the pump holding wall (8), the fuel storage part (9) being provided with a filter (17). The pump holding wall (8) and the second housing (2) are connected to each other via the snap-fit mechanism (55) which is arranged above the enclosure wall (10), or inside the enclosure wall (10) in a planar view. |
