This complete repair solution allows the replacement of worn or damaged high-pressure oil rail ball tubes. This eliminates the need for the costly replacement of the entire oil rail, a common issue on the 6.0L Power Stroke. The ball tubes supply high pressure oil from the oil rail to the injectors. Worn ball tubes or O-rings can leak, resulting in a loss of injection control pressure causing poor engine performance and/or a no-start or hard-start condition. Product Features:Includes four precision machined ball tubesIncludes four OE quality high-temperature O-ringsIncludes special installation tool required to remove and install retaining nutServices the oil rail on one side of engine
