Abstract
An exhaust treatment fluid system includes a tank housing for storing an exhaust treatment fluid. A suction tube includes a first end positioned within the housing and a second end in communication with a suction port of the housing. An elongated laminar flow device is secured to a discharge port of the housing such that exhaust treatment fluid flows along surfaces thereof as the exhaust treatment fluid is returned to the tank housing. The laminar flow device includes a non-circular cross-section.

An exhaust treatment fluid system, comprising:
- a tank housing for storing an exhaust treatment fluid including a suction port and a discharge port;
- a suction tube having a first end positioned within the housing and a second end in communication with the suction port;
- and
- an elongated laminar flow device secured to the discharge port such that exhaust treatment fluid flows along surfaces thereof as the exhaust treatment fluid is returned to the tank housing, wherein the laminar flow device includes a non-circular cross-section.
An exhaust treatment fluid system, comprising:
- a tank for storing an exhaust treatment fluid, the tank being adapted to be fixed to a vehicle;
- a suction tube positioned within the tank;
- an injector including an inlet in fluid communication with the suction tube and an outlet;
- and
