In an activated carbon filter for reducing vapor emissions from a fuel supply system including, in a filter housing, a first connecting section for communication with the atmosphere and a second connecting section for communication with the fuel supply system, an activated carbon filter section is disposed between the first and second connecting sections and a filter layer of a highly adsorptive filler material layer is disposed between the activated carbon filter section and the first connecting section to prevent any escape of vapors through the first connecting section to the atmosphere. |
