ABSTRACT:
An in-tank fuel filter includes a body having upper and lower panels comprising an outer shell or layer of extruded mesh, layers of spun bonded and melt blown filtration media and a fitting for mounting the filter to an in-tank fuel pump inlet. The outer layer of the body is extruded mesh material that has the general appearance of a woven fabric but includes connections at every filament intersection. This outer layer protects the finer, inner filtration layers which include a first layer of spun bonded material, a layer of melt blown filtration media defining smaller pore sizes and a second layer of spun bonded material. The mounting fitting is made of a fuel compatible material and may either be a multiple part device or be in-situ molded on one of the filter panels. Separating ribs or a stuffer may be disposed in the interior of the filter to prevent its collapse and improve fuel withdrawal through the mounting fitting.
