An apparatus and method for sealing and accessing the end of a fill pipe connected to a pressurized fuel reservoir. The cap has a body, a sealing member for sealing between the cap and the adapter ring, a fastening system for fastening the cap body to the end of the pipe, and a valve system for venting the pressurized gaseous media in fuel reservoir. The valve system has an inlet exposed to the pressurized gaseous media contained in the fuel reservoir, an outlet exposed to a volume external to the reservoir. A flow path extends through the cap body between the inlet and the outlet, and a valving member movably disposed in the flow path that is adapted for manual activation to selectively provide fluid communication between the inlet and the outlet.
