NOTE: If you remove the fuel rail lines from the cylinder heads, this kit contains the fuel sleeves for the filter bowl ends only. It is recommended to also replace the sleeves on the cylinder head end of the fuel rail lines once they have been removed as they will no longer seal properly.  Order part GZ-7-004 to supplement this kit.
