Abstract: A device for drying fuel, e.g., in a motor vehicle, has a storage reservoir for a desiccant which absorbs moisture at temperatures below a regeneration temperature, and releases it again at temperatures above the regeneration temperature. Furthermore, a connection between the storage reservoir and a fuel tank storing the fuel is provided, the air situated above the fuel coming into operative connection with the desiccant via the connection. Using a heating device for heating the desiccant to a temperature above the regeneration temperature, the desiccant is able to be regenerated. The device for drying fuel enables removal of water contained in the fuel.
