NHTSA complaint #10458793, filed 2012-05, 102,000 miles

“One of the braided stainless steel fuel lines that attaches to the engines fuel rail developed a leak. I kept smelling a strong odor of gas, but I could not find out where it was coming from. After two weeks of smelling the gas, I took it to a garage and they showed me the gas squirting from the braided hose going to the engine. I took the vehicle to the ford dealer and showed them the leak. They took the vehicle in their shop and removed the fuel lines. Because of the age of the vehicle, ford does not provide any replacement parts. I was unable to get replacement fuel lines from ford. …”
