ABSTRACT:
A fuel system includes a fuel tank and a liquid separator. The fuel tank includes an interior in which liquid fuel and fuel vapor are contained, and has at least one vent in fluid communication with a vapor dome in the interior of the fuel tank. The liquid separator is in fluid communication with the at least one vent in the fuel tank, and has a fuel port disposed at a lower elevation than the at least one vent to enable the liquid separator to be passively aspirated under negative pressure conditions within the fuel tank. The liquid separator may be placed inside or outside the fuel tank.
