I saw this water-heated carburetor spacer this morning on e-bay. It was labeled as "1963-1964 OEM Ford Mustang Falcon V8 260 2V Carburetor Spacer C2OE-9A589-E".

That made me curious, so I looked around and found this:

This spacer must be specific to a 1962 Fairlane. The 260 was introduced in mid-1962 and the intake manifold must have been redesigned for 1963.
The intake manifold that I have on my engine was an e-bay purchase that was said to be an “Original intake manifold off a 1963 Ford 260, casting C30E-9425”, and it does not have anywhere to attach the water inlet that is on that spacer. It also has a PCV valve rather than a draft tube.
The parts diagram shows that the engine could be had with either a PCV valve or draft tube. Was having one or the other determined by its destination market, or by date of manufacture?
I wonder why the water heated carburetor idea only lasted one year.
Was it prone to leaks?
Was the primary reason for the the water passage to heat the carburetor quicker on a cold morning, or would it also keep the carburetor cooler than it would otherwise be while sitting on a hot engine?
