Inline dump-able fuel system dust filter

1. A product comprising:

a dump-able filter comprising:

a filter body;

a filter assembly comprising a filter carrier having at least one slot and a cylindrical filter element surrounding a portion of the filter carrier, wherein the filter assembly is seated in the filter body;

a filter cap, wherein the filter cap attaches to the filter body and encloses at least a portion of the filter assembly;

wherein the filter body comprises an outlet port which is constructed and arranged to connect to a vehicle component; and

wherein the vehicle component is at least one of a fresh air line or a canister vent solenoid (CVS).

2. The product of claim 1 further comprising an O-ring which seats between the filter body and the filter cap to seal the dump-able filter assembly when the filter cap and the filter body are attached together.

3. The product of claim 1 wherein the filter cap interlocks with the filter body when the filter cap is rotated in a first direction onto the filter body and wherein the filter cap unlocks with the filter body when the filter cap is rotated in a second direction.

4. The product of claim 1 wherein the filter cap comprises an inlet port which is constructed and arranged to connect to the vehicle component.

5. The product of claim 4 wherein the vehicle component is at least one of the fresh air line or the canister vent solenoid (CVS), or a pre-filter or an outside air source.

6. The product of claim 1 wherein the filter cap, the filter assembly, and the filter body form an air flow tunnel which directs an air flow through a flow path, wherein fine contaminants in the air flow adhere to the filter assembly and course contaminants drop into at least one contaminant collection chamber in the filter body.

7. The product of claim 6 wherein the air flow enters into the dump-able filter through an inlet port, is directed through a plurality of spiral vanes located in the filter cap, through the filter carrier in the filter assembly, through a center tunnel in the filter body, and exits through an outlet port on the filter body.

8. A product comprising:

a dump-able filter comprising:

a filter body;

a filter assembly comprising a filter carrier having at least one slot and a cylindrical filter element surrounding a portion of the filter carrier, wherein the filter assembly is seated in the filter body; and

a filter cap, wherein the filter cap attaches to the filter body and encloses at least a portion of the filter assembly;

wherein the filter carrier further comprises a hollow body including the at least one slot, a first end constructed and arranged to mate with the filter cap, a second end constructed and arranged to mate with the filter body, and a lip which extends radially from the hollow body adjacent the first end, and wherein the filter element extends around the hollow body of the filter carrier, and wherein the filter element includes a barrier element which is attached to at least one of a bottom surface or a top surface of the filter carrier.

9. The product of claim 1 wherein the filter cap comprises:

a cap structure, wherein the cap structure comprises a top component, a body component, and a plurality of spiral vanes which extend downward from the top component, wherein the body component comprises a first end and a second end, wherein the second end comprises a locking feature which extends radially from the perimeter of the second end and is constructed and arranged to lock together with the filter body; and

an inlet port which extends upward from the top component.

10. The product of claim 9 wherein the filter cap is constructed and arranged to house an O-ring.

11. The product of claim 1 wherein the filter body comprises a cup component having a first end and a second end, and wherein a lip extends radially from the first end and includes at least one locking feature which is constructed and arranged to lock together with the filter cap; a center tunnel which extends inside the cup component having a first end and a second end, wherein the first end is constructed and arranged to mate with a filter carrier; at least one contamination collection chamber interposed between the cup component and the center tunnel; and an outlet port.

12. The product of claim 1 further comprising a fuel system, and wherein the dump-able filter is operatively connected to the fuel system.

13. The product of claim 12 wherein the dump-able filter functions as a part of a path for fuel tank air to be released to the atmosphere during refueling.

14. A product comprising a dump-able dust filter for a fuel system comprising:

a filter body;

a filter assembly comprising a filter carrier having at least one slot and a cylindrical filter element surrounding a portion of the filter carrier, wherein at least a portion of the filter assembly is interposed inside the filter body; and

a filter cap, wherein the filter cap encloses at least a portion of the filter assembly and locks with the filter body;

wherein the dump-able filter is operatively connected to the fuel system and functions as a part of a path for fuel tank air to be released to the atmosphere during refueling.

15. The product of claim 14 wherein the dump-able dust filter is constructed and arranged to remove contaminants from an air flow by sending the air flow through an inlet port on the filter cap, through a plurality of spiral vanes in the filter cap, through the at least one slot, and through the filter element into a center tunnel in the filter body, and out an outlet port on the filter body; and wherein fine contaminants adhere to the filter element, and wherein course contaminants drop out of the flow path into at least one contaminant collection chamber in the filter body.

16. The product of claim 14 further comprising an O-ring interposed between the filter cap and the filter body.
