Zusammenfassung:	A reductant supply system for an engine aftertreatment device is provided. The reductant supply system includes a tank configured to store a reductant. The reductant supply system includes a filter configured to receive the reductant from the tank. The filter defines a filtered volume therein. The reductant supply system includes a suction conduit in fluid communication with the filtered volume. The reductant supply system also includes a pump in fluid communication with the suction conduit. The pump is configured to pressurize the reductant. The reductant supply system further includes a return conduit configured to recirculate at least a part of the reductant pressurized by the pump to the filtered volume.
