I have a fill station in my garage. I got my set up from jegs, I get my NOS 99.99 pure from local weld shop they call it N2O plus. I rent the 90 pound tanks for 10 bucks and get them filled. I get a bunch of local street racers that want there tanks filled. I make good money doing it. The whole fill station from jegs I think I paid $1200 comes with everything even the digital scale.
