I know that you are unhappy with the factory, and frankly, who wouldn't be, but is there anything you can do yourself to sort the problem. It doesn't sound as if it is too difficult to remedy.

Can you, or the dealer, not get another hose which will fit, even if you have to make it up with some joining pieces, it will at least get you up and running for more than an hour.

Do you know what precisely is the problem with the hose?

Maybe you have been down these avenues and are still having problems, if so, my apologies, maybe the answer is to write to the CEO, who is not Mr. Morgan any longer, as I understand it.
