Claim:
A fuel filter comprising a filter housing, a riser pipe arranged vertically within said housing, said riser pipe having an upper end in fluid flow communication with said housing outlet, a particle filter element disposed in said housing between a housing inlet and a housing outlet, said particle filter element arranged over an outside surface of said riser pipe, and a coalescer element improving separation of water from fuel is arranged within said filter housing, said coalescer element arranged over an outside surface of said riser pipe and positioned axially above said particle filter element, said coalescer element being arranged in said housing upstream from the particle filter element so that fuel passing through the filter flows first through the coalescer element and then through the particle filter, wherein said riser pipe in an area of said particle filter element has a openings in a wall of said riser pipe through which filtered fuel from said particle filter flows into said riser pipe and then to said housing outlet through said riser pipe, wherein no prefilter is arranged in said housing upstream of said coalescer element, wherein the coalescer element has no significant particle filtering properties.
