The tail of my Polaris 360 broke off and it needed a new sweep hose barb. I've got it now and am trying to take the old one off. It's not very straightforward and I've had to remove several parts just to get to it. I'm still not really "to" it but I can see where it's attached, however I can't figure out how to remove it. It doesn't seem to pop off or screw off. If I turn it to the left, it tightens and if I turn it to the right, it just turns and turns but isn't coming off. Has anyone ever taken one of those babies apart or know a resource for instructions?
