It's called a CHOKE TUBE MUSHROOM BUTTON for a B manifold.

I've seen them at NPD but it sounds like shipping will cost more than the price or the part. Does anyone else sell them with a more reasonable price for shipping?

Never mind. I found one with help from another member. Thanks anyway.

On this subject.. I've wondered exactly what that button does?. Is it just a plug for the end of the heat tube, or is it intended to let a bit of air into the tube?

It lets air in.  Supplied heat to the automatic choke.  Unfiltered air, what were the engineers thinking?

Unless a dedicated restoration, the 56 setup allows for fresh air source.http://forums.y-blocksforever.com/uploads/images/a4f6891e-11e2-484e-94bd-a728.jpg

I also had to replace the tube noted as 9890 in the diagram.
The 2100 carb shown confuses things a bit if trying to reference the diagram for a 56.

None of the air enters the carb for the fuel/air mix.

It is drawn by manifold vacuum through the choke mechanism and does affect air/fuel ratio. The carb is (was) calibrated at the factory for the extra air ingestion.

Is it a 57 Tbird only thing? I don't remember seeing anything mentioned in the 56 shop manual. I looked at the original teapot from my 56 and I didn't see anything where a tube like this would have attached to it.

No, '57 all (V-8).

The PARTS ILL I posted is what is found in the 49/59 MPC. It is a compilation drawing showing both 56 and 57 systems. It does confuse but when FORD uses engineering drawings for the parts catalog, they only offer enough detail to find the BASIC PN easily.

The 56 setup draws fresh air from the ACL (I believe) and for some reason 57 draws outside unfiltered air. The 56/57 choke was integral to the carb whereas the 55 choke setup was divorced and mounted on the intake.

I hope this helps and if more info is needed or I have posted something incorrectly, ask again.

Here is another photo showing the 56 specific filtered fresh air intake-

I believe the air inlet tube is connected to the 56 specific ACL nipple with a section of vacuum hose.

Keep in mind that while the 1956 ECZ-A 4V intake uses filtered air for the automatic choke, the 1957 and up ECZ-B 4V intake does use the air inlet button at the lower left side of the intake manifold in lieu of using filtered air.  The button does keep the big stuff out like the mud daubers.

That rubber hose isn't hooked up to anything. Should it hook up to something under the air horn?
My old 56 manifold is missing the fitting on that side.

The exposed end of the air inlet in the picture should be going into the bottom of the air cleaner flange portion of the Teapot carb.  That is where the filtered air is sourced for that particular setup.  There is a rubber grommet at the carb for that choke air inlet tube to fit into.  It does become tricky to lower that carb onto the choke tube without bending it.

THANX Ted!

I was under the impression it connected to the ACL. It now makes sense.

Maybe explains why FORD went to the deflector in 1957 as they would have had to design three different tubes (FORD - HOLLEY - CARTER) for that model run unless they sourced the fresh inlet air from the ACL housing..

Still on a learning curve here... Cool
