They might...The other problem is that the regular HPA, CO2 tanks etc. has different fill niples/fittings. You may end up making your own fill station adapter to accept their fittings.I have a scuba cert, but I am looking to HPA for an airgun. I don't think that the 80 cf tank will be much of a problem to fill, as long as I don't tell them what the air is for. Will be used to fill a 13 or 22ci tank up to 3000 psi.
