A jet and venturi tube arrangement is provided for a fuel delivery module. The arrangement includes a venturi tube 14 having an opening 15 , an internal wall 24 and a central axis C. A jet 10' is provided that has an exit 22 . The jet 10' is constructed and arranged to spray a stream 12 of fuel from the exit 22 into the opening 15 of the venturi tube 14 substantially along the central axis C. The jet 10' has surface features 20 , near the exit, constructed and arranged to divert a portion 12' of the stream 12 of fuel so that the portion 12' contacts the internal wall 24 of the venturi tube 14 thereby limiting back flow of fuel through the opening of the venturi tube. |
