A fuel supply system for an internal combustion engine includes a fuel tank and an air supply and venting device for the fuel tank. The air supply and venting device includes a hydrocarbon retention device and an air supply and venting path, structured and arranged to provide a gas exchange between the fuel tank and an environment. The hydrocarbon retention device includes at least one filter membrane that separates hydrocarbons from air. The at least one filter membrane is arranged in the air supply and venting path such that the air supply and venting path is covered by the at least one filter membrane to prevent hydrocarbons from escaping from the fuel tank into the environment through the air supply and venting path. The at least one filter membrane has hydrocarbon nanotubes.
