Yes you will have to empty the tank as it made but, you can either fit an on/off inline tap with a quick release the other side or the other option is to fit a Pro-connect this is in appearance is similar to a quick release the difference is this one hold the air so you can take your tank off, this is the system I have...next if you want to get one...mmm little difficult Rekka do them, 32 Degrees do one as do Boston Paintball Supplies I'm sure there are other suppliers but to get one from the States is by far the cheaper way even with postage.
