Got my Monitor a couple of days ago I bought. It is a Akron 3422 Apollo 3 inch Deck Mount. I had to adapt it to 2 inch since that is the pump size feeding it on my Type 2 Tender. Can't wait till it quits freezing to test the Adjustible 95-200 GPM Akron Turbojet nozzle I put on the end. Thinking of adapting my 4 inch 475 GPM Draft Pump also into it if the 2 inch one does not do a good enought job. Not a bad $250.00 investment! I modified the crank to a handle so it could be moved faster for wildland fires. Mark
