Another question for the experts (regarding 67 GT-350)

[Bossssssss]

Hey Gents - need to ask you another technical question. This time on the vacuum line that runs between the power brake booster and (I believe) to the back of the (Cobra) intake manifold.

I need to know what is correct and what the vacuum line consists of.

On one end, I know there is a rubber line that connects to the check valve on the booster, but what does the other end of the rubber line connect to?

Does the rubber hose connect directly to a fitting that is screwed into the Cobra intake? or does it connect to a steel tube which then is supposed to connect (somehow) to the Cobra intake?  I pasted a link below of the tube in question (which is for a 67-68 small block Mustang), but I assume this is not needed on a Shelby due to the alum Cobra intake?  A pic would be worth a thousand words.

Thanks in Advance!

Yes there is a metal tube with a fitting similar to the one you linked for NPD, I think the correct is available from Deadnutson (?), (there is another thread on this topic that discusses it, may be able to alter the one you reference).

There is a brass fitting that screws into the second vacuum port on the back of the aluminum COBRA intake that the metal tube screws onto.  These are available too, NPD and others, the originals have a W stamped on them.

Will look for links and images, these are 4-speed examples.  (not an expert - just trying to help)

Thanks JD. By the way, my car is a 4 speed (forgot to mention that) as I think the connection/routing may be different between a manual trans vs automatic trans.

If you find those links that would be great.

thanks again!

ok - found a link at NPD for the one fitting:

Just need to find the other fitting and the proper steel tube needed. I did not see anything on Deadnuts which is mostly for 69-70 cars.

I did see a fitting in this kit that NPD sells, but it does not look exact.

verified the line at NPD is correct for a 67 350

Its Classic Tube part number MUO1002-SC

Link to Classic Tube:
https://classictube.com/product/shelby-gt350-350-289-cid-v8-brake-booster-vacuum-lines-1967/

Link to same part number sold by NPD:
https://www.npdlink.com/product/vacuum-line-brake-booster-stainless-steel-by-classic/104346?backurl=search%2Fproducts%3Fsearch_terms%3Dvacuum%252Bline%26top_parent%3D200001%26year%3D1967&year=1967

So I just need the one fitting with the W on it. I don't necessarily need to have the W on it, but I would like to find that part so it looks reasonable correct and most important (to me) is that it (meaning the car) is working properly.

See link (although this is regarding GT500 the tube you're asking about looks very similar), see reply #8, the first image the part shown in the lower half.

The brake booster fitting maybe listed at NPD as

Hey JD - thanks for all your help. Yes that last item you posted from NPD will do the trick for me. Going to place an order for the two fitting and steel line from them. You Rock and Thanks again!
