Abstract: A method for delivering a reductant into a reductant tank through a fill conduit associated with the reductant tank is provided. The reductant tank is in selective fluid communication with an external source having a delivery conduit associated therewith. The method includes connecting the delivery conduit of the external source with the fill conduit of the reductant tank. The method also includes operating a valve provided on the delivery conduit in a first configuration. The method includes changing an operation of the valve from the first configuration to a second configuration. The method also includes purging of a portion of the reductant retained in the fill conduit into the external source through the pump assembly based on the second configuration of the valve.
