ABSTRACT:
A fuel vapor recovery device having: a condenser in communication with fuel vapor from a fuel tank, the condenser condenses fuel from the fuel vapor; a reservoir collecting condensate from the condenser, the reservoir maintains the condensate at a temperature sufficient to maintain the condensate in a liquid state; and return means returning the condensate to the fuel tank. Also disclosed is a method of removing fuel from a fuel vapor including the steps of: passing the fuel vapor from a fuel tank through a condenser; condensing the fuel from the vapor; cooling the condensate to a temperature sufficient to maintain the condensate in a liquid state; and returning the condensate to a fuel tank periodically.
