Abstract

An inline reductant filter assembly includes a filter housing, a filter media, and one or more valves. The filter housing is fluidly coupled to an upstream portion of a reductant line and a downstream portion of the reductant line. The filter media is positioned in the filter housing. The one or more valves are selectively movable from a first position to a second position. In the first position, the one or more valves permit fluid to flow along a first fluid flow path from the upstream portion of the reductant line, through the filter media, to the downstream portion of the reductant line. In the second position, the one or more valves prevent fluid from flowing along the first fluid flow path through the filter media.
