This is my third try to get this post to go through. So somethings going on with this site. If you can’t fill a green bomb, then you’re not gonna be able to refill one of those refillable tanks either. Go online, learn how to do it, get yourself a scale and do it right. You don’t need to mess with that little stater needle,or whatever it’s called, use an Allen wrench through the top to relieve pressure.
