Motorcraft CM5242 is an OE fuel rail O-ring kit for restoring the injector sealing interface on compatible Ford and Lincoln fuel systems. It is built for vehicle-specific service on applications including Ford Focus, F-150, Fusion, EcoSport, Edge, Expedition, Transit vans, Lincoln Continental, MKX, MKZ, Nautilus, and Navigator models.
