Abstract
An apparatus for dispensing volatile liquid fuel with recovery of fuel vapors includes a fuel delivery system having a fuel delivery line and a pump in the line to pump fuel there-along to a nozzle. A vapor recovery subsystem includes a vapor return line from the nozzle and a vapor impulsion means to induce vapor to flow through the vapor return line at a vapor flow rate comparable to the liquid flow rate through the fuel delivery line during most of a fueling operation. A vapor impulsion booster boosts the vapor flow rate above the liquid flow rate early in a fueling operation.
