Abstract
A fuel-feeding unit for supplying a fuel from a fuel tank is described which has a particularly compact structure. The described fuel-feeding unit has a fuel pump driven by an electrical motor, a low pressure side preliminary fuel filter and a high pressure side main fuel filter arranged in a housing. The housing has a central compartment for the electrical motor and a circular compartment surrounding the central compartment in which the main fuel filter is located. The housing is closed and sealed by means of a housing cover that has a fuel outlet connector and an E-connector for electrical power lines. The pump impeller of the fuel pump arranged in a pump compartment inside the housing has a diameter which is larger than the diameter of the central compartment and the fuel is fed from the fuel pump directly into the circular compartment.
