Original distributor vacuum advance control valve, also called a ported vacuum switch (PVS) valve, that was installed on all Ford models including Mercury Cougar, Ford Mustang, and Torino starting in 1967.
This is a used original pot metal and brass part. It has the FORD oval logo and part number D0AE-A casting.This casting number is correct for all 1970 1971 1972 and 1973 Fords and Mercury. It was used on all engine options including 302 351C 351W 429 and 429CJ models. Because of the heavy demand placed on the cooling system by the factory air option this was mounted on the water outlet fitting. It's job was to switch the vacuum source for the distributor from the carburetor to the intake manifold when the water temperature went above normal. This would cause more advance, a faster idle and more water circulation. These are often broken or scarred by improper removal attempts. This is a rare original hard-to-find part and is a must-have item if you place your classic in Concours judged shows. Will likely show some wear, often times the soft pot metal will have some erosion present. We are not able to test these for function or accuracy. Sold as-is. Marked D0AE-A, original Ford part number D0AZ-12A091-A.
NOTE: This is similar to valves used on the 68-69 models which had C8AE-A casting.
