Abstract
A system for providing fuel to an engine fuel delivery system and to an exhaust aftertreatment system associated with an engine. The system includes a fuel source, a pump being operable in a first state to pump fuel from the fuel source to the engine fuel delivery system, and the pump being operable in a second state to pump fuel from the fuel source to the exhaust aftertreatment system, wherein the first state corresponds to a first rotational direction of the pump and the second state corresponds to a second rotational direction of the pump.
