ABSTRACT:
A vehicle refueling system and a vehicle refueling method are disclosed. The refueling system includes a filler cup, a nozzle seal in the filler cup for sealing to a filler nozzle, a vapor re-circulation path from the gas tank to the filler cup, and an air relief module. The air relief module provides additional air to the filler cup region below the nozzle seal when the vapor re-circulation path does not provide sufficient make-up air to the filler nozzle during refueling operations. The refueling method includes providing air through an air relief module when the vapor flow through the vapor re-circulation path is not sufficient to perform a refueling operation.
