Abstract: A filter device has a sub-tank to be provided in a fuel tank. The sub-tank has an outer tubular portion and a bottom wall. A communication hole is formed in the bottom wall. An upper-side filter element is fixed to an upper side of the bottom wall to form an upper-side filter space between them, while a lower-side filter element is fixed to a lower side of the bottom wall to form a lower-side filter space between them. An inlet port of a fuel pump is connected to the upper-side filter element. Apart of fuel can be reserved in a fuel holding portion of the inside of the sub-tank and/or in the upper-side filter space, even when fuel amount in the fuel tank is decreased and the fuel tank is inclined with respect to a horizontal line.

Abstract: A fuel supply device includes a pump unit that sucks stored fuel in a fuel tank from a suction port and discharges the fuel to an outside of the fuel tank. A pressure regulating valve performs pressure regulation of fuel discharged from the pump unit. The pressure regulating valve includes a return port having an opening facing in a separating direction away from the suction port, and returns surplus fuel generated by the pressure regulation from the return port into the fuel tank. A suction filter encloses an internal space where the suction port is open, and filters the stored fuel entering the internal space. The suction filter includes an expansion part to which the internal space is extended, and the expansion part is on a side of the return port that faces in the separating direction.

Abstract: A suction filter includes: a casing having an intake port through which fuel is drawn; a filtration object to filter the fuel to be drawn into the intake port; and a wall component which defines a fuel passage for fuel which passes the filtration object toward the intake port. At least a part of the filtration object is located upper than the intake port. The wall component has an upper end positioned upper than the intake port, and the fuel passage is defined so that the fuel flowing through the fuel passage flows over the upper end.
