ABSTRACT:
A fuel delivery system including a fuel tank having multiple sections. A fuel pump is disposed in a first section with an inlet for drawing liquid fuel from the first section and an outlet for supplying the fuel to an engine and to a pick-up disposed in the second section. A siphon line is connected to the pick-up at one end and terminates in the first section at another end. A fuel inlet of the pickup communicates with the siphon line through a valve member that is actuated to open and closed positions. In operation, the fuel pump provides a flow of liquid fuel to the pick-up to purge and prime the siphon line which normally maintains a substantially equal liquid fuel level in the first and second sections of the fuel tank. In some conditions, the valve closes to prevent reverse flow of fuel from the first section to the second section of the tank.
