Abstract: A water separation group (1) for a fuel filtration and separation assembly (900) of a fuel circulation system of a vehicle, wherein the assembly (900) comprises an assembly casing (950) which extends along a longitudinal axis (L-L) positionable in the vehicle in a horizontal position and accommodating a filtration group (500) for filtering dirty fuel. The water separation group (1) is in turn positionable in the assembly casing (950) in fluidic connection with the filtration group (500) and extends along a main axis (X- X) parallel to and/or coincident with the longitudinal axis (L-L). The water separation group (1) comprises a separator device (2) and a blocking device (3) positioned below the separator device (2) to prevent the return of the separated water to the separator device (2). The blocking device (3) comprises a blocking surface (31) which extends in a longitudinal direction forming an angle with the direction of the main axis (X-X) that inclines at least a portion of said blocking surface (31) so as to allow the water separated from the fuel to flow towards the wall from which it extends.
