A fuel system for a motor vehicle includes a fuel pump having a first pump outlet connectable to an engine fuel inlet and a second pump outlet, a fuel pump module including an internal volume, a fuel pump module outlet is arranged in the internal volume fluidically connected to the second pump outlet, and a fuel valve is fluidically connected to the second pump outlet. The fuel valve is operable to fluidically isolate the fuel pump from the fuel pump module when fuel in the internal volume reaches a selected fuel level.

Fuel system for a motor vehicle

A fuel storage assembly includes a power source, a first tank, a fuel pump, an electric relay, a second tank, and a shut-off device. The fuel pump is adapted to remove fuel from the first tank. The electric relay is electrically connected between the power source and the fuel pump for terminating electric power to the fuel pump. The second tank is adapted to receive the fuel removed from the first tank. The shut-off device is located in the second tank and is electrically connected to the electric relay, and is configured to detect a shut-off level of fuel in the second tank. Upon detection of the shut-off level, the shut-off device effects shut-down of the fuel pump via the electric relay.
