D0ZZ-6A664-A Original used hose that connects the original threaded PCV valve combination with C7OZ-6A706-A elbow and the carburetor spacer plate. Molded hose with 5/8" valve end and 3/8" spacer plate end. 1970 428CJ and 428SCJ engines, includes Cougar and Mustang only. Used hoses will have faded striping (if present), and clamp impressions. Very often the rubber will be hard and showing some degree of stress cracks.
*Note - Excludes 1967-69 S code 390-4V and 1968-69 428CJ engines. See part number C7ZZ-6A664-B.
*Note - These molded and contoured hoses were designed to work with original style PCV valve (modern 90° PCV valves won't work). Additionally anything other than period original intake manifolds, valve covers, and spacer plates can also alter the position and distance in the relationship of the PCV valve and carburetor spacer plate.
