The two 6" long rubber hoses that connect the fuel tank to the intermediate fill tube and the intermediate fill tube to the fill spout have cracks in them and are leaking fuel. I called WRV and talked to Mark in service and he told me any 2" diameter diesel fuel hose will work for this application. His only tip was the fuel tank side has a barbed nipple on it so the hose will need to be cut to remove it. My Alpine is a 2000 so any other Alpines of this same age may have a similar problem. I also wonder if the ultra low sulfur fuel may have contributed to this problem.
