What is claimed is: 1. A cap for covering an opening of a spout, the cap comprising: a top defining an inner surface and an outer surface; an engagement portion extending from the inner surface and adapted to engage the spout; a wall extending from the inner surface to define a container-receiving space; and a pierce point extending from the inner surface and at least partially disposed within the container-receiving space, the wall and the pierce point fixed with respect to one another. 2. The cap of claim 1, wherein the engagement portion includes threads integrally-formed as part of the engagement portion. 3. The cap of claim 1, wherein the top, the engagement portion, and the wall are integrally-formed as a single piece. 4. The cap of claim 1, further comprising an engagement member coupled to the wall and adapted to engage a reservoir. 5. The cap of claim 4, wherein the wall defines an inner cylindrical surface and the engagement member includes a slot extending at least partially around the inner cylindrical surface. 6. The cap of claim 4, wherein the engagement member includes threads formed as part of the wall. 7. The cap of claim 1, wherein the pierce point is integrally-formed as part of the top. 8. A cap configured to cover an opening of a spout of a fuel container and hold a reservoir that contains a fuel additive that is delivered to the fuel container after the reservoir is retained by the cap, the cap comprising: a lop defining an inner surface and an outer surface; an engagement portion integrally-formed as part of the top and extending from the inner surface, the engagement portion adapted to engage the spout; a wall integrally-formed as part of the top and extending from the inner surface to define a space; a pierce point extending from the inner surface and adapted to pierce the reservoir to enable the fuel additive to be released from the reservoir; and a reservoir-engagement member disposed substantially within the space and adapted to engage the reservoir to hold the reservoir at least partially within the space. 9. The cap of claim 8, wherein the engagement portion includes threads integrally-formed as part of the engagement portion. 10. The cap of claim 8, wherein the wall defines an inner cylindrical surface and the reservoir-engagement member includes a slot extending at least partially around the inner cylindrical surface. 11. The cap of claim 8, wherein the reservoir-engagement member includes threads formed as part of the wall. 12. The cap of claim 8, further comprising a pierce point extending from the inner surface into the space. 13. The cap of claim 8, wherein the wall and the pierce point are fixed with respect to one another. 14. A cap for covering an opening of a spout, the cap comprising: a top defining an inner surface and an outer surface; an engagement portion extending from the inner surface and adapted to engage the spout; a wall extending from the inner surface to define an inner cylindrical surface and a container-receiving space; a pierce point extending from the inner surface, the wall and the pierce point fixed with respect to one another; and one of a slot and a tab extending around at least a portion of the inner cylindrical surface and adapted to engage the other of the slot and the tab of a reservoir. 15. The cap of claim 14, wherein the engagement portion includes threads integrally-formed as part of the engagement portion. 16. The cap of claim 14, wherein the top, the engagement portion, and the wall are integrally-formed as a single piece. 17. The cap of claim 14, further comprising a pierce point that extends from the inner surface and is at least partially disposed within the container-receiving space. 18. The cap of claim 17, wherein the pierce point is integrally-formed as part of the top. 19. A cap adapted to cover a spout and support a reservoir, the cap comprising: a shell including a top portion and an engagement portion extending from the top portion, the engagement portion adapted to engage the spout; a reservoir engagement member extending from the shell and adapted to engage the reservoir; a pierce point coupled to the shell and positioned to puncture a portion of the reservoir, the reservoir engagement member and the pierce point fixed with respect to one another. 20. The cap of claim 19, wherein the top portion, the engagement portion, and the reservoir engagement member are integrally-formed as a single piece. 21. The cap of claim 20, wherein the pierce point is integrally-formed as a single piece with the top portion, the engagement portion, and the reservoir engagement member. 22. The cap of claim 19, wherein the reservoir engagement member defines a reservoir space and wherein the pierce point extends from the top portion and is at least partially disposed within the reservoir space. 23. The cap of claim 19, wherein the reservoir engagement member defines an inner cylindrical surface and a slot extending at least partially around the inner cylindrical surface. 24. The cap of claim 19, wherein the reservoir engagement member defines an inner cylindrical surface and includes threads formed as part of the inner cylindrical surface.
