ABSTRACT:
An in-line fuel reservoir for a high pressure fuel metering system having a high pressure pump for pumping fuel to an engine and a low pressure pump for pumping fuel from a fuel tank to the high pressure pump. The fuel reservoir has a fuel supply chamber, a fuel supply inlet to the fuel supply chamber which is coupled to the low-pressure pump, a fuel supply outlet from the fuel supply chamber which is coupled to the high pressure pump, a fuel return inlet coupled to the engine, a fuel return outlet coupled to the fuel tank, a first fuel opening between the fuel return inlet and the fuel supply chamber, a second fuel opening between the fuel return inlet and the fuel return outlet and a valve assembly for controlling the flow of fuel through the first and second fuel openings to direct returned fuel to the fuel supply chamber and the fuel tank. The full reservoir may also include a vent opening between the fuel supply chamber and the fuel return outlet to vent vapor and fuel from the fuel supply chamber.
