Abstract
A process comprising fueling a tank, collecting emitted vapors, and recovering condensed vapors. In the process, gasoline is discharged into a fill opening or filler pipe of a tank through a fuel outlet conduit of a nozzle. Gasoline vapors emitted during fueling are collected with a vapor return conduit of the nozzle and conveyed through a vapor return hose. A portion of the gasoline vapors in the vapor hose are condensed and removed from the vapor hose with a condensate pickup tube extending from the nozzle.
