Abstract

A high-pressure fuel feed pump, wherein a pump housing is formed with an aluminum alloy, a cylinder is formed with an iron base metal, the flange part of a flanged tubular member is held in a contact part between the pump housing and the cylinder, and the tubular member is installed in the pump housing along the inner wall surface thereof, whereby a seal surface is not corroded directly because a cavitation occurs between the tip of the tubular member and the pump housing.
