摘要: A fuel filter device is provided in which a filter assembly having filter layers of first multiple layers is provided in a fuel flow path extending from the interior of a fuel tank to fuel consumption means via a fuel pump, and the finest filter layer is disposed downstream-most in filter layers of second multiple layers forming at least part of the first multiple layers, wherein an aggregation-promoting part (24A) that promotes aggregation of dust in fuel by changing the flow direction or flow velocity of fuel is provided in the filter assembly (20A) so that aggregation of dust in fuel is promoted before the upstream side of at least the second finest filter layer (22A) of the filter layers (21A, 22A, 23A) among the second multiple layers. This enables the durability of the fuel filter device to be improved.
