Method of installing an anti-siphon assembly

1. A method of installing an anti-siphon device in a fuel filler neck, comprising:

mounting a plurality of retainer clips on an elongate spring that includes only a single circular loop;

mounting a plurality of locator clips on said elongate spring, said locator clips each including a locator surface;

placing said elongate spring, with said plurality of retainer clips and said plurality of locator clips mounted thereon, into a fuel filler neck that defines a circular interior surface such that said single circular loop of said spring is positioned adjacent to and extends around said circular interior surface of said fuel filler neck, until said locator surface of each locator clip contacts an upper surface of said fuel filler neck; and

securing said retainer clips to said circular interior surface of said fuel filler neck.

2. The method of claim 1 further comprising removing said plurality of locator clips from said elongate spring and from said fuel filler neck after said retainer clips are secured to said circular interior surface of said fuel filler neck.

3. The method of claim 2 further comprising placing an anti-siphon device into said fuel filler neck such that said anti-siphon device is supported by said retainer clips.

4. The method of claim 3 wherein said anti-siphon device is structurally distinct from said elongate spring and is positioned radially inwardly of said elongate spring.

5. The method of claim 1 wherein said securing said retainer clips comprises adjusting a fastener within said retainer clips such that said fastener contacts said circular interior surface of said fuel filler neck.

6. The method of claim 1 wherein said mounting a plurality of locator clips on said elongate spring comprises positioning said elongate spring within a hook of each of said locator clips, said hook positioned distal from said locator surface on each locator clip.

7. The method of claim 1 wherein said mounting a plurality of retainer clips on said elongate spring comprises positioning said elongate spring within a recess of each of said locator clips.

8. The method of claim 1 wherein an outer diameter of said anti-siphon device is smaller than an inner diameter of said fuel filler neck.

9. A method of installing an anti-siphon assembly, comprising:

providing a spring that defines only a portion of a single circumferential loop;

mounting a retainer clip on said spring, said retainer clip including a support surface adapted to support an anti-siphon device thereon; and

mounting a locator clip on said spring, said locator clip including an outwardly extending arm adapted to contact an upper surface of a fuel filler neck opening.

10. The method of claim 9 wherein said spring comprises a leaf spring and wherein said portion of said single circumferential loop of said leaf spring defines a substantially circular shape.

11. The method of claim 10 wherein said retainer clip is mounted radially outwardly of said spring.

12. The method of claim 9 wherein said retainer clip includes a recess, and wherein said spring is received within said recess.

13. The method of claim 9 wherein said locator clip includes a hook positioned distal from said outwardly extending arm, said method further comprising releasably mounting said hook on said spring.

14. The method of claim 9 wherein said retainer clip includes an aperture extending therethrough and a fastener movably secured within said aperture, said method further comprising securing with said fastener said retainer clip to an interior wall of a fuel filler neck.

15. The method of claim 9 further comprising:

mounting a second a retainer clip on said spring, said second retainer clip including a support surface adapted to support an anti-siphon assembly thereon; and

mounting a second locator clip on said spring, said second locator clip including an outwardly extending arm adapted to contact the upper surface of a fuel filler neck opening.

16. A method of installing an anti-siphon assembly, comprising:

providing a spring that defines a length and wherein an entire length of said spring consists of only a portion of a single circle;

mounting a retainer clip on said spring, said retainer clip including an aperture extending therethrough and a support surface;

movably positioning a fastener within said aperture;

positioning said spring within a fuel filler neck such that said entire length of said spring is positioned adjacent to a cylindrically shaped interior surface of said fuel filler neck and biases said fastener into contact with said interior surface of said fuel filler neck so as to retain said retainer clip thereon; and

positioning an anti-siphon device on said support surface of said retainer clip.

17. The method of claim 16 wherein said spring comprises a leaf spring that defines a substantially circular shape, wherein said spring biases said retainer clip radially outwardly and into contact with said interior surface of said fuel filler neck.

18. The method of claim 17 wherein said retainer clip is mounted radially outwardly of said spring.

19. The method of claim 16 wherein said retainer clip includes a recess, and wherein said spring is received within said recess.

20. The method of claim 16 further comprising mounting a second retainer clip on said spring, said second retainer clip including a support surface adapted to support said anti-siphon assembly thereon.
