Fuel filter comprising: - a receptacle comprising a base portion (BP) forming a bottom and a cover detachably connected to the base portion (BP), the receptacle being provided with an inlet for unfiltered fuel (CB) and an outlet for filtered fuel (FC) which is located in the base portion (BP), an inside volume (V) being defined between the base portion and the cover, - a filter insert arranged in the inside volume (V) and having an upper axial end including a first flange , preferably engaged against the cover , a lower axial end, and a substantially annular filter medium extending about a longitudinal axis (A) between the upper axial end and the lower axial end, the filter medium having an inner face which defines a hollow internal space in communication with the outlet , - a central member extending in the hollow internal space , having a first end directly integral or adjacent to the first flange and a second end opposite to the first end, - a transverse wall (P) extending beneath at least one among the lower axial end and the central member, defining a passageway (VP) between the hollow internal space and the outlet , characterized in that the transverse wall (P) also defines, parallel to the passageway (VP), a discharge passage for conveying gases (GC) contained in the fuel to an escape channel that is distinct from the inlet and the outlet , a longitudinal channel provided in the central member allowing circulation of these gases, which are accumulated at a high point of the inside volume, to the discharge passage so that they pass through the transverse wall (P) via said passage before joining the escape channel , and in that the fuel filter further comprises a valve enabling selectively opening the passageway (VP) in an operative configuration of the filter insert under the effect of an engagement between the second end of the central member and said valve which is mounted so as to move relative to the transverse wall (P), the central member thereby being an actuating member for moving the valve according to the position of the filter insert , the valve by default being biased toward a position which closes the passageway (VP). - a receptacle comprising a base portion (BP) forming a bottom and a cover detachably connected to the base portion (BP), the receptacle being provided with an inlet for unfiltered fuel (CB) and an outlet for filtered fuel (FC) which is located in the base portion (BP), an inside volume (V) being defined between the base portion and the cover, - a filter insert arranged in the inside volume (V) and having an upper axial end including a first flange , preferably engaged against the cover , a lower axial end, and a substantially annular filter medium extending about a longitudinal axis (A) between the upper axial end and the lower axial end, the filter medium having an inner face which defines a hollow internal space in communication with the outlet , - a central member extending in the hollow internal space , having a first end directly integral or adjacent to the first flange and a second end opposite to the first end, - a transverse wall (P) extending beneath at least one among the lower axial end and the central member, defining a passageway (VP) between the hollow internal space and the outlet , <EOS>
