摘要： A pump unit having a fuel pump and a suction filter is provided in a sub tank of a fuel tank. A filter element sheet for the suction filter is formed in a cup shape, a bottom wall portion of which faces to an inner bottom surface of the sub tank. A suction port of the fuel pump is opened to a fuel passage formed in the inside of the suction filter, so that filtered fuel is sucked into the fuel pump. Multiple mountain fold portions and multiple valley fold portions are formed on a side wall of the cup-shaped filter element sheet, to thereby increase surface area for filtering the fuel.

摘要： A stop valve which is fitted with a cylindrical supporting portion is comprised of a ring-shaped rigid axial portion, a ring-shaped platy bendable valve portion extending outward, and a sealing lip portion extending inward. The sealing lip portion has a first sealing lip which extends obliquely upward from the rigid axial portion and has a semi-circular seal effecting face provided at an edge thereof, and a second sealing lip which extends obliquely downward from the rigid axial portion and has a semi-circular seal effecting face provided at an edge thereof. The first and second sealing lips have an extending portion which connects the edge seal effecting face with the rigid axial portion and has substantially a same thickness as a diameter of the semi-circular shape.
