The impeller includes upper and lower vanes that move fluid through upper and lower portions of a semi-circular pumping channel, respectively. An exhaust port extends through the module housing and communicates with an exit passage of the pumping channel. An arcuate trench is disposed in the upper wall of the module housing and communicates with the outlet end of the pumping channel to redirect exiting fuel upward from the pumping module to a fuel pump housing outlet. The exit passage of the pumping channel extends tangentially outward into the trench. so that fuel exiting the pumping channel is relatively unimpeded.
