ABSTRACT:
A filler neck for mounting between a fueling port and a fuel tank entry nipple provides a fuel path into the tank and a vapor recovery path from the tank while being serviced from a fuel dispensing nozzle having vapor recovery means. The filler neck comprises a fuel delivery tube having a plurality of ribs on its outside surface and connected into the inside of the tank entry nipple. A sleeve tube is slipped over the fuel delivery tube and is connected at one end to the fueling port and at the other end to the outside of the tank entry nipple. The relationship between the tubes and the tank entry nipple is such that a vapor path exists in the valleys defined by the ribs on the fuel delivery tube.
