    摘要： A vehicle having an engine, a fuel tank, and a pump encased in a housing. The pump is in fluid communication with the fuel tank and the engine. A filter is disposed intermediate the fuel pump and the engine. An electrical conductor having an inoperative position and an operative position is operatively associated with the pump. When the filter is installed, the electrical conductor contacts the pump housing to ground the pump allowing operation thereof.

    摘要： 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.

    摘要： In operation, the main pump (24) is activated and the main value (18) is opened in response to the ignition switch (28) being turned ON to pump fuel from the fuel supply tank (12) to the injectors in the injector manifold (14). During the ON condition, the return control valve (48) is closed to prevent back flow from the injector manifold (14) to the fuel tank (12). In response to the ignition switch (28) being turned to the OFF condition, the main valve (18) is closed and the main pump (24) is deactivated and, most importantly, the return control valve (48) is opened and the return pump (40) is activated to place a negative or vacuum pressure on the upstream side of the injectors to return the residual fuel therein to the fuel tank (12). This prevents the residual fuel from leaking through the injectors and into the combustion chambers of the engine (10), which, in turn, would make it difficult to immediately restart the engine (10) because of a fuel rich condition.
