A header assembly for an aftertreatment system includes: a header including: a suction port, and a return port; a first splitting device configured to receive a first flow of reductant from the suction port and to split the first flow into a first inlet flow and a second inlet flow; a second splitting device configured to receive a first outlet flow and a second outlet flow and to provide a second flow to the return port of the header; a first inlet line configured to direct the first inlet flow to a first dosing module; a second inlet line configured to direct the second outlet flow to a second dosing module; a first outlet line configured to direct the first outlet flow to the second splitting device; and a second outlet line configured to direct the second outlet flow to the second splitting device.

Reductant tank assembly with multiple connection tank header

An aftertreatment system includes a first dosing module, a second dosing module, and a reductant tank assembly. The reductant tank assembly includes a reductant tank, a header coupled to the reductant tank, and a first splitting device that splits a first flow from the header into a first inlet flow and a second inlet flow. A first inlet line and a second inlet line direct the first inlet flow and the second inlet flow to the first dosing module and the second dosing module. A first outlet line and a second outlet line direct a first outlet flow and a second outlet flow from the first dosing module and the second dosing module to a second splitting device. The second splitting device merges the first outlet flow and the second outlet flow into a second flow and provides the second flow to the header.
