Yup, Same fault, just occured. It seems to split at the bottom of the hose ....
Mine suffered the same fate
the next indication is when you fill up and fuel starts pouring out over the exhaust when you fill up with petrol.
This happened to me also - not pleasant.
The replacement hose cost £111.08. I trust at this price it's Ethanol resistant.
Despite much correspondence the factory denied that this was a 'known problem'.

Maybe now they'll acknowledge there's a problem and do something about it?
