A fuel drip retention system includes generating a vacuum in an evaporation line 50 between a fuel nozzle receiving port 40 and a vapor canister 60. The vacuum is generated upon determining that fuel has stopped flowing into a fuel tank to draw any remaining fuel droplets that remain on the nozzle. The vacuum may be generated by actuating one of a pump 120 or a starter motor (110 fig. 2).
