An apparatus for introducing fluid having a volatile organic component from one container, for example, a fuel storage vessel to a receiving container such as an on-board fuel storage tank of an automotive vehicle with reduced discharge of organic vapors into the surrounding atmosphere, the apparatus including a filler cap having at least one positively sealing quick connect fitting through which fluid can be introduced which is releasable attachable with a mating fitting located on the filler nozzle of an external fluid delivery device. The apparatus also including at least one vapor conveying fitting located in the filler cap which is matingly engagable with a fitting located on an externally positionable organic vapor conveying conduit located in proximity to the fluid dispensing nozzle such that, when engaged, a circuit is completed wherein fluid is introduced into the receiving container such as the on-board fuel tank of an automotive vehicle and any organic vapors displaced during the operation are returned to the storage container without contact with the surrounding environment.
