A system for refilling a reductant tank of a first machine is provided. The system includes a reductant reservoir, a first valve, and a pump. The first valve is fluidly connected to the reductant reservoir. The pump is fluidly connected to the first valve. Further, a nozzle is fluidly connected to the first valve. The first valve provides a reductant flow from the reductant reservoir to the pump, and from the pump to the nozzle when in a first position, and reverses the reductant flow from the nozzle to the pump, and from the pump to the reductant reservoir in a second position. Also, a pilot line is selectively associated with an outlet of the pump and the first valve. When pressure between the pump and the nozzle exceeds a threshold, pilot pressure causes the first valve to shift from the first position to the second position.
