Abstract
The invention relates to a fuel delivery unit () that is disposed in the fuel tank () of a motor vehicle, the delivery unit comprising a level sensor () that detects when the amount of fuel in a surge chamber () falls below a minimum amount. When the fuel in the surge chamber () falls below a defined minimum, the supply of power to a delivery pump () that is driven by an electromotor is interrupted, thereby preventing the delivery pump () from delivering air when the surge chamber () is empty.
