Abstract
A vehicle fuel system for use in a vehicle having an engine. The system includes a fuel tank having a fuel pump module area and a bulk area, and a fuel pump mounted in the fuel pump module area, having an inlet and an outlet. A thermostatic valve has a fuel inlet connected to a return fuel line from the engine, a first outlet and a second outlet, with the valve directing fuel through the first outlet when the temperature is below a threshold and directing fuel through the second outlet when the temperature is above the threshold. A cold fuel line connects to the first outlet of the valve and directs fuel to the fuel pump inlet, and a warm fuel line connects to the second outlet of the valve and directs fuel into the bulk area of the fuel tank away from the fuel pump.
