ABSTRACT:
An in-tank fuel filter includes a body comprising layers of spun bonded and melt blown filtration media and a fitting for mounting the filter to an in-tank fuel pump inlet. An outer layer of the body is preferably spun bonded material which exhibits good abrasion resistance. One or more inner layers of melt blown filtration media define smaller pore sizes and thus exhibit smaller particle filtration capability. The mounting fitting is made of a fuel compatible material and may either be a multiple part device or be in-situ molded on the filter body. A separator may be disposed in the interior of the filter to prevent its collapse and improve fuel withdrawal through the mounting fitting.
