The elongate elastic core extends between the first and second ends of the elastic shoelace, and the sheath includes an outer surface and surrounds the elongate elastic core. The method for adjusting the width of particle thickness size distribution of the flakes of material so formed includes the step of varying the distance between the cup, or the disc, and the entrance to the gap between the plates until the desired particle size distribution is obtained. A bottom portion of the receiving portion and an end portion of the filter element defines therebetween an outflow chamber for storing fuel. The first tube engages the threaded insert for micro adjustment of the set length to a locked length.
