Abstract
A semi-open staggered vane impeller for use in an automotive fuel pump. Each vane has a cover-side vane tooth and a body-side vane tooth extending from a central vane groove. Each vane is coupled to the next adjacent vane by a rib that runs substantially parallel to the vane groove. In addition, each vane has a phase difference between its cover-side vane tooth and body-side vane tooth that is a function of the length of the vane groove.
