Abstract

A fuel feed pump for a motor vehicle, wherein a liquid sealing portion is formed in a position close to an impeller in a casing, an exhaust port is opened in the intermediate portion of the liquid sealing portion in a manner to communicate the inner space of the liquid sealing portion with the outside of the casing. The casing is opened therein with a deairing hole for communicating the liquid sealing portion with the outside of the casing. A deairing groove is formed at least on the upper end surface of the casing. One end of the deairing groove is communicated with the upper space of a generally annular groove path and the other end is communicated with the deairing hole, traversing the liquid seal portion.
