Abstract
An abrasion wear resistant fuel pump for a vehicle includes a pump section having a flow channel and a rotatable impeller cooperating with said flow channel to pump fuel therethrough. The fuel pump also includes a motor section disposed adjacent the pump section and having a motor to rotate the impeller. The fuel pump further includes an outlet section disposed adjacent the motor section to allow pumped fuel to exit the fuel pump. The pump section includes a plurality of plates disposed axially adjacent to and cooperating with the impeller. The impeller and plates are made of a composite material that improves abrasion wear characteristics therebetween.
