Abstract
A fuel filler pipe for a fuel filler system of an automotive vehicle includes a generally helical directional control surface disposed within the fuel filler pipe and extending along the longitudinal axis thereof. The directional control surface guides fuel flowing through the filler pipe so as to impart a spiral flow to the fuel such that the fuel flows with reduced turbulence and subsequent vapor generation. In addition, the directional control surface restricts backward flow of fuel from the fuel tank through the fuel filler pipe.
