Abstract
A feed device for fuel has a feed pump driven by an electric motor and a housing which receives the electric motor. The feed pump and a filter arrangement which has a preliminary pump and a main pump arranged respectively before and behind the feed pump in the fuel flow direction are provided in the housing. The feed pump transports the main flow of fuel through a central recess in the filter pot at the input flow side of the main filter of the filter arrangement. A side channel pump which is open on one side is arranged at the feed pump as a preliminary stage thereof. The fuel can be delivered subsequent to the preliminary filter to a rise pipe and then into a pot housing to a suction area of the main stage of the feed pump.
