Abstract: An apparatus for introducing fuel having a volatile hydrocarbon component into an on-board fuel storage tank of an automotive vehicle with reduced discharge of fuel vapors into the surrounding atmosphere, the apparatus including a fuel filler cap having at least one centrally positioned aperture extending therethrough through which a suitably configured fuel directing nozzle can pass. The fuel directing nozzle includes a vapor conveying line located in the interior of the nozzle capable of being brought into fluid communication with a vapor collection chamber located in the fuel filler cap such that, when engaged, a circuit is completed, fuel can be introduced into the on-board fuel storage tank of the automotive vehicle and any fuel vapors generated or displaced during the operation can be returned to the remote storage site or another suitable vapor collection facility remote from the automotive vehicle without contacting the surrounding environment.
