Fuel Pump and Fuel Supply System Using the Same

A fuel pump includes a motor having an armature which rotates about an axis, the motor also having a stator which circumferentially surrounds the armature such that a fuel passage is defined between the armature and the stator, whereby rotation of the armature induces a circumferential flow of fuel within the fuel passage; a pumping arrangement which is rotated by the armature and which pumps fuel from a first inlet to a first; a second inlet which introduces fuel into the fuel passage; a second outlet which discharges fuel from the fuel passage; and a flow impedance member in the fuel passage which impedes the circumferential flow of fuel within the fuel passage, thereby generating a pressure gradient across opposing sides of the flow impedance member such that fuel entering the fuel passage is pumped to the second outlet.
