Abstract: 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.

Abstract: A filter includes a filter element (1) having a filter medium (106) pleated in a zigzag manner, with a raw side (105) and a clean side. On the raw side (105) and/or on the clean side of the filter medium (14; 106), a plurality of oblong adhesive sections (122) are disposed along at least two adhesive tracks (101) on the filter medium (106), which run obliquely or perpendicularly to the pleat edges (F) at least in some sections.
