D0AZ-6A664-C Original used hose that connects the valve cover mounted PCV valve and the carburetor spacer plate on 1970 Mercury Cougar and Ford Mustang 351 Cleveland engines both 2 and 4 barrel versions."L" shaped hose, 1/2" in diameter, approximately 15-1/4 inches long. 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 1969-70 351W or Windsor engines.
*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.
