For this reason, the pressure regulator 24 and the piping members 59 and 60 can be compactly arranged between the set plate 15 and the canister 26.

  A cover member 28 is provided to cover the suction filter 22 provided at the suction port 42 of the fuel pump 20 (see FIG. 7). For this reason, the movement of the fuel in the cover member 28 when the vehicle jumps or turns can be suppressed. As a result, the fuel shortage phenomenon that the fuel pump 20 cannot absorb the fuel can be prevented or reduced. This can be said to be particularly effective as a motorcycle and an ATV pump module 10 in which the amount of movement of fuel in the fuel tank 12 is larger than that of a four-wheeled vehicle.

  Further, the return fuel discharged from the pressure regulator 24 is received in the cover member 28 via the return fuel hose 77 (see FIG. 7). For this reason, the fuel shortage in the cover member 28 can be prevented or reduced.

  In addition, the return fuel discharged from the downstream end of the return fuel hose 77 flows out or is applied to the filter medium 62 of the suction filter 22 (see FIG. 7). As a result, a fuel liquid film can be formed on the surface of the filter medium 62 and air inhalation of the fuel pump 20 can be prevented. Therefore, when the remaining amount of fuel is small, even if a part of the suction filter 22 is exposed from the fuel, air can be prevented from being sucked by the fuel liquid film, and the function of the fuel pump 20 is not impaired. Can prevent burnout. Further, the dust collected on the surface of the filter medium 62 of the suction filter 22 can be removed from the filter medium 62 by the return fuel. As a result, clogging of the filter medium 62 due to dust can be prevented or reduced, and the life of the filter medium 62 can be improved.
