Abstract: An integrated reductant supply system includes a reductant tank, a reductant dosing module selectively couplable to the reductant tank, an aftertreatment control module coupled to the reductant tank and in electrical communication with the reductant dosing module and a connector, and an integrated reductant supply system component. The aftertreatment control module is configured to control dosing of reductant from the reductant dosing module, and the connector configured to electrically couple to an equipment manufacturer component. The integrated reductant supply system component is coupled to the reductant tank and includes one or more of an ambient temperature sensor, a solenoid valve, a reductant level sensor, a reductant delivery line, a reductant return line, a coolant inlet line, a coolant return line, a filter, a mounting bracket, an AOS, or a wiring harness.
