TMFarm - Theo is correct about the pivot tube and the air coming out the bottom of the pivot tube. Mounting the tube in a solid pipe without a bottom outlet for the airline coming out the bottom of the receiver tube sleeve could be a problem you will need to trouble shoot. Before buying a wmill email me for scanned images from the instrucion manual so you will know what you are mechanically going to have to deal with.
