A vapor recovery nozzle, comprising:
- spout means for dispensing liquid volatilizable hydrocarbon fuel into a fill opening of a tank;
- vapor collection means for collecting volatilized hydrocarbon vapors emitted from said tank concurrently during said dispensing, said vapor collection means including passage means for passing said vapors to a vapor return line, and at least some of said vapors condensing to form condensate, wherein said vapor collection means includes a vapor inlet positioned in proximity to said spout means;
- condensate withdrawal means for substantially removing said condensate in said vapor return line so as to substantially minimize blockage of vapors passing through said vapor return line;
- and
- automatic shutoff means for stopping the dispensing of fuel when said fuel enters said vapor inlet, wherein said automatic shutoff means includes a liquid sensing tube disposed along said spout means, within said passage means and extending to a position adjacent said vapor inlet.
