Fuel supply device, particularly for an internal combustion engine

A fuel supply device (1) for an internal combustion engine (6), comprising;

• a particulate filter and
• a water separator, wherein the water separator (5, 8, 30) is embodied as a separate component downstream of the particulate filter (4) and comprises
• a first separating stage (A1) with hydrophilic coalescent material as well as
• a second separating stage (A2) with hydrophobic material and wherein the separating stages (A1, A2) are arranged such that between them a diversion of the fuel is realized;
• wherein the water separator (8) comprises a substantially cylindrical housing (9) whose longitudinal axis (L1) is at least approximately vertical;
• and
• wherein arranged in the housing (9) an insertion element (10) is provided that comprises a vertical tube section (15);
• wherein an interior of the tube section (15) defines a fuel outlet passage;
• wherein the tube section (15) has an axial upper end which leads fuel to a fuel outlet:
• wherein fuel flows axially within the interior of the tube section (15) in a direction from an axially opposing lower end of the tube section (15) to the axial upper end;
• wherein a plate-shaped guiding element (18) is arranged on and secured onto the axially opposing lower end of the tube section (15), the plate-shaped guiding element (18) closing off the interior of the tube section at the axially opposing lower end of the tube section (15), the plate-shaped guiding element (18) extending radially outwardly away from the radial outer surface of the tube section (15) and beyond the hydrophobic material to form a radially outwardly extending guide surface on which separated water is guided radially outwardly to an annular gap (26) surrounding the plate-shaped guiding element (18).
