What is wrong: The steel fuel return tubes that connect the frame fuel return lines with the engine fuel rail can contact the pinch weld flange connecting the dash panel to the floor pan. Continued contact leads to abrasion of the steel fuel return tube and eventually results in a fuel leak.
Risk: Abrasion of the steel tube wall that eventually causes a fuel leak may result in a fire, if a source of ignition is present.
Remedy: Ford dealers will replace the fuel return tubes with flexible stainless steel braided/teflon tubes. Dealers will also inspect the fuel supply tubes.
