Abstract
A fuel pump for a motor vehicle has an outlet duct leading to an internal combustion engine and a connection leading to an ejector, and two delivery chambers which are separate from one another. The delivery chambers are concentric so that one surrounds the other. The fuel pump is simple to construct and can be manufactured at favorable cost.
