Thanks @Silver, that sorted it out... Nice and snug, like it should be. Just wrapped around 3 times. Easy solution
Mine was really so loose that it could fling it off waving the tank around when its lubed with juice.
Ok that's great to hear!!
I am going to do that tonight too.
Mine is not as loose as yours though - so probably just one or maybe two wraps of dental floss will do.
Glad its sorted for you.
