The method of claim 11, where the dye is a naphthalimide.13. The method of claim 1, wherein the fluid includes a lubricant.14. The method of claim 1, wherein the fluid system is a heating, ventilating, or air conditioning system.15. The method of claim 1, wherein ambient pressure is atmosphere pressure.16. A method for introducing fluid into a heating, ventilating, or air conditioning system comprising:filling a container with a fluid including a dye; attaching the container to a fluid delivery apparatus, the fluid delivery apparatus including: a body having a cavity, an output port fluidly connected to the cavity, an input port fluidly connected to the cavity by a channel, and a piston orifice fluidly connected to the cavity; a piston extending into the cavity through the piston orifice; an intake valve within the channel; an output valve proximate to the output port; and a pressure valve between the intake valve and the input port; transferring a fluid from the container into a cavity of the fluid delivery apparatus, thereby reducing pressure in the container; introducing the fluid from the cavity into the fluid system; and equalizing pressure within the container to ambient pressure. 17. The method of claim 16, wherein attaching the container to the fluid delivery apparatus includes threadably connecting the container to a threaded input port of the fluid delivery apparatus.18. The method of claim 17, wherein the threaded input port is threaded at a thread density of 8 threads per inch, and has an inner diameter of 22 mm and a thread diameter of 24.1 mm.19. The method of claim 16, wherein the container includes a neck, the neck having a thread density of 8 threads per inch, a pitch of 3.18 mm, a helix angle of 2°34′, an outer orifice diameter of 21.5 mm, and a thread diameter of 23.7 mm.20.

The method of claim 16, wherein the container has a four fluid ounce nominal capacity.24. The method of claim 16, wherein the container has a two fluid ounce nominal capacity.25. The method of claim 16, wherein the fluid delivery apparatus comprises a pressure valve to equalize pressure in the container.26. The method of claim 16, wherein the fluid includes a dye.27. The method of claim 26, where the dye is a naphthalimide.28. The method of claim 16, wherein the apparatus further comprises a suction tube fluidly connected to the channel.29. The method of claim 28, wherein the suction tube extends from the channel, through the input port and into a container.30. The method of claim 29, wherein the container has a height of 135 mm, and an outer diameter of 50.8 mm, and the suction tube has an outer diameter of 6 mm and a length of 162.8 mm with a 16° bend from vertical directed towards the output port starting at 71.25 mm from a fluid receiving end of the tube.31. The apparatus of claim 29, wherein the container has a height of 100.9 mm, and an outer diameter of 42.5 mm, and the suction tube has an outer diameter of 6 mm and a length of 124.2 mm with a 16° bend from vertical directed towards the output port starting at 55.2 mm from a fluid receiving end of the tube.32. The apparatus of claim 29, wherein the container has a height of 73.0 mm, and an outer diameter of 35.3 mm, and the suction tube has an outer diameter of 6 mm and a length of 102.2 mm with a 16° bend from vertical directed towards the output port starting at 42.2 mm from a fluid receiving end of the tube.33.
