FIELD OF THE INVENTION [0002]The present invention relates to a vent arrangement and, more particularly, to a cap for a fuel tank or remote vent for a fuel system and including a membrane. SUMMARY OF THE INVENTION [0003]In independent aspects and in some constructions, the invention provides a cap for closing an opening, such as the filling tube on a fuel tank, the cap generally including a cap housing operable to close the opening, a structure supported by the housing and defining a vent, the vent allowing the flow of gas (e.g., air) therethrough, and a membrane positioned in a flow path and presenting flow of one or more selected fluids (e.g., liquid, fuel, harmful gases, etc.) from existing the vent. [0004]In independent aspects and in some constructions, the invention provides a vent for a closed system, such as a fuel system, the vent generally including a vent housing in fluid communication with the system, a structure supported by the housing and defining a vent, the vent allowing the flow of gas (e.g., air) therethrough, and a membrane positioned in a flow path and preventing flow of one or more selected fluids (e.g., liquid, fuel, harmful gases, etc.) from exiting the vent. In some constructions, the vent generally includes a remote vent. [0005]Independent features and independent advantages of the present invention will become apparent to those skilled in the art upon review of the detailed description and drawings.
