Abstract
A fuel feed pump for a motor vehicle, in which a liquid- tight portion is formed in a position close to an impeller inside a casing, an exhaust port forms an opening in the middle part of the liquid-tight portion so as to connect the internal space of the liquid-tight portion to the outside of the casing. The casing has, formed in it, a ventilation hole for connecting the liquid-tight portion to the exterior of the casing. A ventilation groove is formed at least on the upper terminal surface of the casing. One end of the ventilation groove communicates with the upper space of a generally annular arrangement of recesses and the other end communicates with the ventilation hole, passing through the liquid-tight portion. <IMAGE>
