ABSTRACT:
A fuel pump assembly includes a container with the removable cover which forms an enclosure for a pump and a replaceable filter element which is disposed in coaxial surrounding relation to the pump. The filter element includes an upper end cap having an end wall forming an annulus, and a downwardly-extending side wall which forms a central cavity. The lower end of the side wall includes a radially inwardly-directed flange which defines an annular opening. A ring seal is disposed within this lower annular opening in the side wall. The filter element also includes a lower end cap which has an annular spacer collar with axially-upwardly extending tabs. A tubular filter media is disposed between the upper and lower end caps and secured thereto with a potting compound. Side wall 82 extends downwardly through the center of the filter media such that the tabs on the spacer collar on the lower end cap contact the ring seal on the upper end cap. The pump is inserted within the cavity defined by the side wall on the upper end cap such that the ring seal seals against the lower end of the pump around the pump inlet. Fuel flows radially inward and then axially downward through the filter media, radially inward and then axially upward through flow paths between the tabs on the spacer collar on the lower end cap and the ring seal, and then axially upward to the pump inlet. Outwardly-projecting ridges or spacers are provided around the circumference of the upper and lower end caps, and axially downwardly-extending fins are provided on the lower end cap, to provide an offset between the filter element and the container for fuel flow therebetween.
