Abstract
A filter for use with a fuel system having contaminants has a plurality of apices and a plurality of ridges, where each ridge attaches an apex to an adjacent apex. A plurality of ridges and adjoining apices define a first opening that is in register with a second opening wherein the second opening has less surface area than the first opening. A side attaches the first opening and the second opening and tapers inwardly from the first opening to the second opening to minimize stagnant areas along the ridges and apices.
