1. A dosing module, comprising:
a frame assembly comprising a plurality of panels;
a first manifold coupled to one of the plurality of panels, the first manifold being configured to separately receive air and reductant, and the first manifold comprising a first connector extending from the first manifold;
a first dosing tray, the first dosing tray comprising:
a first base panel;
a second manifold coupled to the first base panel, the second manifold being configured to separately receive air and reductant from the first manifold and to provide the air and the reductant back to the first manifold;
a second connector extending from the second manifold, the second connector being configured to be selectively coupled to the first connector;
a first valve coupled to the second manifold and configured to receive at least one of the air or the reductant from the first manifold;
a second valve coupled to the second manifold and configured to receive at least one of the air or the reductant from the first manifold;
a first rail assembly comprising:
a first member coupled to one of the plurality of panels; and
a second member coupled to the first base panel and slidably coupled to the first member such that the first dosing tray is selectively movable relative to the first member.
