An internal housing is surrounded by an external housing, forming an external space. A total quantity of fuel, pumped by the fuel feed pump into the external housing is divided in such a manner into two subquantities of fuel such that the subquantity of fuel, required by a motor, flows out of the fuel feed pump after flowing through the external space and an internal pump housing space. The other subquantity of fuel flows to a pressure regulator without flowing through the external and internal spaces of the pump.
