I have a couple older Wary Avi Vests that I would like to refilled. I know they are out of business and no longer build them. I am guessing there are still a ton of them out there being used, and hoping to get a little information on how to rebuild them? I bought a rebuild kit but it only came with 10 super tiny O-rings, a t pin, and 10 red circle stickers and some grease. I wasn't able to get the puncture disc or the resetting tool. I found a user manual, but it doesn't give any info on how to rebuild the cylinder. Any help I can get is greatly appreciated.
