Anyone have one they can measure?

The 3/4” tube only came in one length. It’s definitely a tiny bit smaller in diameter at the end that fits into the lower part end of breather stand. I recommend using a bit of lock tight at that location.

The inner baffle tube came in two lengths as noted above. I think the shorter of the two came on the vehicles with the factory aluminum intake manifold. The Green Book will confirm that. You cannot mix the two baffle applications, nor can either be easily modified to work in the other applications.

Although the shorter tube at 4-1/2" is the most popular they did come with the longer depending upon the intake manifold. The 35-36 restoration book explains the difference in the intake manifolds designs. Photo below shows the two. 34 and early 35 intakes used the longer tube as well maybe others. It's a good idea for the questioner to tell the year of the vehicle being worked on.

1935, early intake is what I am working with

Below is another photo of the early 35 intake manifold with it's round hole under the fuel pump riser for the internal baffle tube. The baffle tube and the tube off the fuel pump riser are the longer style due to the height of the fuel pump riser surface on the intake.

That is the same one I have, round hole as well!!!
