Fuel delivery device

The fuel feed system (2) is mounted inside the fuel tank (1) in a road vehicle. There is an inner container (3) with a submerged fuel pump (4). An intermediate feed container (8) overflows into the inner container. Some of the fuel from the engine fuel feed pipe (5) is returned to the fuel tank. It passes through a venturi pump (6) into a feed pipe (7) with a ventilating system (10,11) in its end (9) entering the intermediate feed container.
