wanted a 10 lb nitrous tank

[stardust]

I remember someone had a 10lb tank with a dip tube, and the cert had run out? Still out there?

You can check craigslist and racing forums for people that may have a 10# or 20# nitrous tanks.

I have two and am willing to unload one. Whatcha got in mind? Cash or barter?

You can find them on ebay as well. You could also convert a Co2 tank by changing the valve to a cga 326 or cga 660 valve.
