Abstract
A filter arrangement disposed in a fuel tank of an automotive vehicle has a flat upper section made of mesh. A lower section made of mesh is joined to the upper section to define a space between the upper and lower sections. The space is filled with fuel filtered by the upper and lower sections and communicates with a fuel pump. The upper and lower sections are different in shape and therefore deform differently under suction due to operation of the fuel pump. This prevents the filter arrangement from collapsing under suction, thereby effectively ensuring a fuel flow passage leading to the fuel pump.
