Abstract
An impeller for a fuel pump for supplying fuel to an automotive engine from a fuel tank includes an impeller body having a substantially disk shape with opposing first and second faces and an outer circumference. The impeller body defines a rotational axis extending therethrough perpendicular to the first and second faces. A plurality of radially outwardly extending vanes extend from the outer circumference of the impeller body and are spaced circumferentially about the impeller body. Each of the vanes includes a first half extending from the outer circumference adjacent the first face and a second half extending from the outer circumference adjacent the second face. The second halves are rotationally shifted about the rotational axis relative to the first halves. The vanes are spaced un-evenly and in a non-repeating pattern about the outer circumference of the impeller body.
