Abstract
A fuel tank for motor vehicles of the type having a filler neck, a fuel tank vent line and a receptacle for insertion of a pump nozzle connected therein is improved by constructing the receptacle so as to at least partially surround a pump nozzle inserted therein in close proximity thereto and by having the receptacle create a hollow space in conjunction with a wall of the filler neck that is closed on a side facing into the fuel tank but has openings on an opposite side communicating outwardly from the tank, the fuel tank vent line terminating in the hollow space. In accordance with the above concept, preferred embodiments of the invention enable air vented by the vent line to pass directly into the filler neck upstream of an outlet of the pump nozzle so that entrainment of fuel particles in air vented therefrom, including associated splattering thereof, is effectively precluded.
