Abstract
An apparatus for recirculating fuel vapors in a vehicle. The apparatus includes a filler head connected to a fuel vapor conduit and a tubular aspirator located within the filler head. The aspirator has at least one orifice in its side wall so that when fuel flows through the aspirator when the vehicle is refueled, a low pressure area that draws fuel vapors through the orifice and into the fuel flow within the aspirator is created.

An apparatus for recirculating fuel vapors, the apparatus comprising:
- a fuel vapor conduit;
- a filler head connected to the fuel vapor conduit;
- and
- a hallow tubular aspirator open at both ends and being located within the filler head, the aspirator having at least one orifice in a side wall thereof, wherein in use, a fuel flow through the aspirator draws the fuel vapors through the at least one orifice and into the fuel flow within the aspirator.

An apparatus for recirculating fuel vapors from a fuel tank, the apparatus comprising:
- a fuel conduit connected to the fuel tank;
- a fuel vapor conduit connected to the fuel tank;
- a filler head having a first end and a second end and connected to the fuel conduit and the fuel vapor conduit, the filler head adapted to accept a nozzle that dispenses fuel at the first end;
- and
- a hallow tubular aspirator open at both ends within the filler head, the aspirator having a first end proximate the first end of the filler head and at least one orifice passing completely through a side wall of the aspirator near the aspirator first end to connect an internal portion of the aspirator to an internal portion of the filler head.
