Many of us have dealt with cracked and/or leaking fuel line hoses. To include the Hydro-Hot and generator. A good replacement is:

I've queried several owners of 2006 models and fuel hose problems don't seem to occur in these and earlier models. Our vehicle was made in 2005 on an early delivery basis. That means the chassis could very well go back to 2004.
