FoMoCo script oval and C8AZ-6A664-D part number properly ink stamped in white. Correctly formed 90 bends. Cut hose as required. These were painted Ford blue along with the rest of the engine. Dual outside diameter hose: 13/16 inch O.D. & 3/4 inch O.D. x 5/8 inch I.D hose. This hose will require both 6A664-2K and 6A664-6AK clamp kits.
For 64-66 Mustang, Falcon and Fairlane: This hose can be used but needs to be modified slightly by trimming both ends slightly and removing the ink stamps as originals were only marked 78FH. When installing, you will need to twist the hose 90 to mate up with the carb spacer and PCV valve. The larger diameter hose end goes to the carb spacer and the small diameter goes to the PCV valve.
See 6A664-2K, 6A664-6AK for hose clamp options.

I had to trim it to fit my application, probably because I am using a police interceptor manifold, but overall it is a nice product.
