ABSTRACT:
A known fuel filter is formed by a meshed body in a bag shape made of a synthetic resin while the meshed body is penetrated to form a fuel passage which is open toward the inside of the meshed body. The known fuel filter is attached to a portion adjacent to a bottom of the fuel tank for preventing water and a dust accumulated inside the fuel tank from being drawn inside the fuel filter. However, the known fuel filter has the fuel passage penetrating the central portion of the meshed body so that the degree of freedom of attachment is reduced. On the other hand, a fuel filter according to the present invention comprises a piece of meshed body being folded double, an outer flange and an inner flange respectively having a fuel passage and being connected to each other from the inside and the outside of the doubled folded portion, a swollen supporter provided integrally with or separately from the inner flange. The peripheries of three sides of the meshed body are welded and the fuel pipe is connected to the outer flange. With such an arrangement, the fuel pipe can be installed along the side wall of the fuel tank. The swollen supporter may comprise a flat plate and a projecting wall projecting from the flat plate which crosses a longitudinal direction of the flat plate while a trimming hole is provided at a central portion of the flat plate and the swollen supporter is cantilevered so that the swollen supporter can be swung vertically.
