Abstract
An adapter defining a transition between a motor vehicle fuel filler pipe having a concentric vapor exhaust passage and a motor vehicle fuel filler pipe having a parallel vapor exhaust passage. The fuel filler pipe having a parallel vapor exhaust passage includes a rigid stem accessible from outside of the motor vehicle, a flexible hose attached to the rigid stem, and a parallel hose connected to the rigid stem by an upper fluid connector. The filler pipe having a concentric vapor exhaust passage includes a rigid outer tube on the fuel tank and a rigid inner tube inside of the rigid outer tube and cooperating therewith in defining a concentric vapor exhaust passage around the rigid inner tube. The adapter according to this invention includes a sleeve between the flexible hose and the rigid outer tube and a baffle in the sleeve concurrently funneling liquid fuel from the flexible hose to the rigid inner tube while diverting displaced fuel vapor in the concentric vapor exhaust passage into the parallel vapor exhaust passage through a fluid connector on the sleeve.
