Did you try an original Ford/Merc tube? We don't even know if the manifold is too big or the tube is too small. (Knowing Speedway, I'd bet on the tube being wrong.) If you have a dial calipers, perhaps measure the hole in the manifold and post it here; I'm sure someone can measure theirs so you can make a comparison. I would, but I'm 2200 miles from my shop for the next week.

I am going to make the assumption that you don't have either the original oil file tube or road draft tube for the engine.
