Abstract
A vehicular fuel system includes a suction pump having an inlet and an outlet, a priming pump having an inlet and an outlet, a valve and a fluid conduit assembly having a first port coupled to the outlet of the priming pump, a second port coupled to the inlet of the suction pump, and a third port coupled to the valve. The fluid conduit assembly and the valve are configured such that when the priming pump is operated, fluid flows from the outlet of the priming pump, through the first port and second ports, and into the inlet of the suction pump and when the suction pump is operated, fluid flows through the valve and the third and second ports, and into the inlet of the suction pump.
