Nitrous Oxide - i need a list of most common needed nitrous fittings and accesories,

Ive talked our local Advanced auto parts(beings how our shop is about their bigest customer) into carring some common NOS fittings and accesories. he said to get him a list and he would stock some stuff. If you have ever tried to put a nitrous system togather in a small town that doesnt have a speed shop than you know the importance of this, not having to wait 3-4 days for a 10 dollar fitting. Everyones input is appreciated.
Thanks
Walt

Thanks fellas. It means a lot when sponsors post on a thread like this one. I appreciate it.
Prime example: Tonite while hooking up a "put togather" kit on my vert I would have given my left nut for a piece if 3/16 stainless tubing about 2 ft long. i had some and made it work but it would have ben nice to go to the parts house and pick some up.
Thanks again
