Abstract

The invention relates to an ejector pump for transporting fuel in a fuel container. Said pump comprises a separate nozzle insert (7) with a nozzle channel (8). The nozzle insert can either be injection moulded from plastic or can consist of metal. The nozzle channel (8) can have a particularly small diameter as a result of the small component size if the insert is made of plastic, or by choosing metal as the material for said nozzle insert. The ejector pump is characterised by a particularly low pumping fluid consumption.
