Abstract

A fuel conveying device having a pumping stage, an electric motor to drive the pumping stage, a control unit, a magnetoresistive fill level sensor that generates a fill level signal, including a temperature-effect compensator that generates a compensation signal to compensate for temperature-related influences on the fill level signal, and an evaluation unit (5) designed such that the temperature of a fluid surrounding the fill level sensor can be determined by the evaluation unit by the compensation signal. A fuel tank equipped with a fuel delivery device of said type, a method for determining the temperature of a fluid inside a fuel tank, a method for controlling and/or regulating an electric motor, and a method for controlling and/or regulating an injection of fuel vapors to a combustion process of an internal combustion engine.
