A fuel supply device in which an electric motor and a fuel pump are accommodated and held in a pump housing having an intake port, a discharge port, and a deaeration hole, and an intake filter for filtering fuel in a fuel tank is connected to an intake port; wherein a gas-phase portion in a fuel tank (5) and a deaeration hole (15) are communicated by a passage (41), the pressure of fuel discharged from a discharge port (14) is detected by a detection means (45), and when the detection value of the detection means (45) is lower than the pressure of states of no clogging in an intake filter (39), a filter clogging determination means (46) determines that there is clogging in the intake filter (39). It is thereby possible to quickly and accurately perceive that there is clogging in the intake filter. |
