This hot air pipe was on my 1926 Model T coupe which was equipped with a Holley NH carburetor when I bought it in 1970. What years does this hot air pipe fit? Did it fit other carburetors besides the Holley NH? Thank you. Jim Patrick

See Dan's post below.

I am not seeing the pronounced flattened area to clear the late adjuster. This one looks like pre 25.

That pipe appears to be identical to the one on my '27 which is also equipped with an NH.

25-27 heat pipe on the right. Note the face relief on the right to clear the mixture/choke rod for 25-27 carburated engines. Both fit on the late, beefier style exhaust manifold.

Correct John, and here is comparisons to the earlier heat stove pipes.

The late pipe is recessed at the upper side to clear the new combo choke and carb adj. rod with the universal joint.

That new assembly was shown in the July 1925 Service Bulletin.
