Abstract

An apparatus for delivery of fuel from a storage tank to an internal combustion engine of a motor vehicle includes a pot-shaped container secured in the storage tank and a pump for delivery fluid from the storage tank into the container. An electric motor drives the pump. A second pump driven by the same electric motor delivers fluid from the container to the internal combustion engine. The second pump is located with the electric motor in a common housing. A pumping chamber is formed at an outer side of the bottom of the container, and the first mentioned pump has a delivery member located in the pumping chamber and driven by this electric motor.
