Abstract
An in-tank module with an electrical fuel pump in a reservoir in a main fuel tank of a vehicle. A filter sock on the bottom of the tank has an outlet in direct communication with the main pump inlet so the pump can prime directly from fuel in the main tank. A secondary fuel outlet in the reservoir and in communication with the pump inlet, is controlled by a valve which opens the secondary fuel outlet when the main pump inlet is starved by reason of low fuel in the main tank. A filter element, above the secondary fuel outlet, filters fuel flowing from the reservoir to the pump outlet when the control valve is open.
