ABSTRACT:
A sealing assembly is provided for use in a filler neck sized to receive a fuel-dispensing nozzle. The sealing assembly includes an elastic seal member between the filler neck and a fuel-dispensing nozzle and a seal retainer for clamping the seal member in the filler neck to define in the filler neck an outer chamber communicable with the atmosphere and an inner chamber. The seal is configured to admit the fuel-dispensing nozzle into the inner chamber without coupling the inner and outer chambers in vapor communication. The sealing assembly partitions a fuel-conducting passageway in the filler neck to limit flow of vapors and gases through the passageway during dispensing of fuel into the filler neck and past the sealing assembly.
