Diesel exhaust fluid system having a reservoir spacer

A diesel exhaust fluid system comprising:

• a fluid reservoir having an inner surface, a wall and an opening defined through the wall;
• a fluid pump in fluid communication with the fluid reservoir through a reservoir tube in fluid communication with the opening through the fluid reservoir, the fluid pump draws fluid from the fluid reservoir through the opening through the fluid reservoir with the reservoir tube;
• a fluid reservoir heating device positioned wholly within the fluid reservoir;
• a fluid reservoir spacer positioned within the fluid reservoir interconnecting the inner surface of the fluid reservoir and the fluid reservoir heating device, the fluid reservoir spacer positioned adjacent to the wall and comprising first and second portions, the first and second portions of the fluid reservoir spacer being arranged such that the opening through the fluid reservoir is positioned between the first and second portions of the fluid reservoir spacer;
• and
• a fluid filter positioned between the opening of the fluid reservoir and the reservoir tube such that the fluid pump draws fluid from the opening of the fluid reservoir through the fluid filter via the reservoir tube.

An automotive exhaust system comprising:

• a diesel combustion engine;
• an exhaust manifold coupled to the diesel combustion engine, the exhaust manifold having a passageway extending therethrough;
• and
• a diesel exhaust fluid subsystem coupled to the exhaust manifold, the diesel exhaust fluid subsystem comprising:
• a fluid reservoir having an inner surface and an opening defined through a bottom portion of the fluid reservoir, the fluid reservoir being in fluid communication with the passageway through the exhaust manifold through the opening;
• a fluid reservoir heating device positioned within the fluid reservoir;
• a fluid reservoir spacer positioned wholly within the fluid reservoir adjacent to the bottom portion and between the inner surface of the fluid reservoir and the fluid reservoir heating device, the fluid reservoir spacer comprising first and second portions on opposing sides of the opening through the fluid reservoir;
• a fluid filter disposed in a housing separate from the fluid reservoir, the housing coupled to the bottom portion of the fluid reservoir adjacent to the opening;
• and
• a fluid pump including a reservoir tube in fluid communication with the opening through the fluid reservoir such that activation of the fluid pump causes diesel exhaust fluid in the fluid reservoir to be drawn through the opening, through the fluid filter, through the reservoir tube and into the passageway through the exhaust manifold.
