Okay. Try this. The feeder pipe splits on your polaris 360, what do you do?? If it’s right up against the nut, you’ll have to cut the nut off. No other way unless you want to sit there for an hour and pull the hose out of the nut with a needle nose pliers.
If it’s three feet or so from the nut and you can not get the nut off, run the pipe of your extension pole through the hose from the other side to the connection (swivel). That will give you a better grip on the hose so you can turn the nut. Also, The nut does not have to be that tight. I use the o-ring lube on the nut to make them easier to turn off.
