Yes, she has tried 2 different Ford dealers and contacted ford but they show no parts available. It is a special fitting that connects to the gas tank. The line is approximately 22.5 feet long! She is in contact with a place in Michigan that says they MAY be able to make the line if she sends them one of the damaged ones. Apperantly, Ford changed their design in 2007 and must mot have made a change over kit available. I don't think I want a motor home on a Ford chassis, she has been stranded in Iowa for almost 2 weeks.
She has tried the site you suggested with no luck, but thank you!
On edit, I think the part fit up through 2011.
