  • Patent number: 7217361
    Abstract: A filter includes first and second axially spaced end caps having filter media extending axially between the end caps and extending in a closed-loop around a perimeter defining a hollow interior communicating with an axial flow opening through one of the end caps. One or more columns extend axially in the hollow interior between the end caps and are laterally spaced from the axial flow opening and have hollow sub-interiors for receiving one or more posts extending axially thereinto from a base for mounting the filter to the base in axial compression and with a wiper seal.
    Type: Grant

  • Patent number: 6464870
    Abstract: A fuel filter assembly adapted for disposition in a housing includes an inner filtration element, an outer conductive surround and end caps which position and secure the filtration element and conductive surround. The filtration element preferably includes an outer layer of depth filtration media and an inner pleated paper element. The conductive surround is preferably conductive extruded plastic mesh. The end caps may be formed of a fuel tolerant plastic such as nylon or acetal. The filter assembly may be disposed in a housing having suitable inlet and outlet fittings and a conductive path for achieving electrical conductivity from the exterior of the housing to the conductive surround for facilitating draining off of an electrical charge.
