Fuel Hoses Lines/piping And Fittings problems of the 2010 Volkswagen CC

I have owned a 1997 vw eurovan camper for 3 years. It is only driven half a dozen times a year and is garage stored. Two years ago, upon start up, I noticed the smell of fuel (gasoline) and found it spraying from a fuel filter connection beneath the vehicle. I took it to a vw dealer, who replaced the crimp connections to the filter. Now again last month, the same problem has recurred. The leak appears to be coming not from the crimped fuel-line, but from some sort of quick-connect type of fitting that connects to the lower filter. Note that the problem only seems to occur upon start-up in the morning, but disappears some time later, so that when the vehicle is taken in to a dealer, there is no leak to be observed. From looking on the internet, I have found that 1993 eurovans were subject to a recall in canada for leaking fuel lines, but nothing ever in the us. Evidently, the problem is still ongoing as I have read dozens of complaints and postings on the internet that described fuel leaks here in the us, some of which indicate fuel leak-related fires have completely burned eurovans to the ground. I have also read that vw dealers are denying there is even a problem.
