A major part of this setup, never cheap out. You do not want to deal with any sealing issues. You can buy it from paintball stores or some diving equipment stores.
Plug your tank into fill station, and make sure vent valve is sealed. Turn on the main release valve on scuba tank to release air and fill up your HPA tank.
Once the refill is finished, turn off the scuba tank release valve first. Then open the vent valve to release pressure. Then you can take off the HPA tank.
