Claim 17:
18. A method of manufacturing a filter element comprising:
integrally forming a first end cap with a first portion of an air-bleed conduit, the first portion axially extending from an inlet formed through the first end cap to a first distal end defining a first distal opening;
integrally forming a second end cap with a second portion of the air-bleed conduit, the second portion axially extending from an outer opening formed through the second end cap to a second distal end defining an inner opening;
providing a ring of filter media circumscribing a central cavity and extending axially between a first end a second end;
affixing one of the second end cap to the second end of the filter media or the first end cap to the first end of the filter media;
connecting the first portion and the second portion of the air-bleed conduit together thereby forming a fluid tight connection; and
affixing the other one of the first end cap to the first end of the filter media or the second end cap to the second end of the filter media.
