Abstract

In a fuel delivery unit for a motor vehicle, having a delivery pump which has a preliminary stage and a main stage, an outlet channel of the preliminary stage is guided radially outward and configured such that it rises upward. An inlet channel of the main stage is guided laterally past the preliminary stage. In accordance with this design, impellers of the delivery pump can be arranged particularly low down and gas bubbles are guided away out of the preliminary stage in a very simple manner.
