Abstract:
1. A fuel filter arrangement for removing foreign particles contained in fuel at a fuel intake side of a pump main body, which discharges the fuel toward a fuel injector, the fuel filter arrangement comprising a fuel filter main body, which is formed as an integral body and includes an inner filter and an outer filter, wherein: the inner filter and outer filter are contiguous so as to be seamlessly joined together; the inner filter includes fibers arranged at a first density; the fibers of the inner filter include pulp fibers; the outer filter is arranged at outside of the inner filter and includes fibers arranged at a second density, which is lower than the first density; and the fibers of the outer filter include pulp fibers, wherein the outer filter includes a plurality of protrusions disposed at equal intervals along an outer peripheral surface of the outer filter and protruding radially outwardly from the outer peripheral surface of the outer filter so that when said fuel filter main body is disposed in a sub-tank structure of a fuel tank assembly, said protrusions engage an inner surface wall of the sub-tank to reduce conduction of vibrations from a pump disposed within the fuel filter arrangement to the sub-tank.
