Packard Forum Index » Post-War (1946-54)

I recently bought a 21st series Custom with an electromatic clutch that I'd like to get operational (dreaming again!). It is missing 2 of the 1/2" steel tubes that go from the big control valve. I have lots of photos and have looked at the Training Manuals in the site but I can't find a photo that shows the connection where the tubing connects directly to the intake manifold. There is a 3/8" threaded plug that screws into the intake manifold so I know that's where it connects but I don't know what Packard used to make that final connection (tubing all the way? hose? some kind of an adapter that connects? I'd like to have it connected the way it's supposed to be connected.
Can anyone in the Forum take that valuable photo so I can connect the vacuum tube like it is supposed to look?
Much, Much appreciated!

The tube from the manifold to the E.clutch is all steel with flared ends to hold the fittings. I belive the fitting in the manifold to which the E.clutch fitting is attached has a tapered pipe thread but with an inside thread and flange to accept a 1/2" flared tube and fitting. Attached are photos showing the tube. I can take a photo of the tube ends if that will help.
I have several E.clutch parts which I no longer need if you will PM me your needs.

I think you need this style inverted flare fittingfittingsandadapters.com/inflartubcon.html for the manifold but don't know if Packard might have used steel.

Thank you so very much for the photos and scans. It tells the story and now I know what I need to adapt to the tubing.
As the car isn't runnung I don't know what parts I need. I'll sure keep this in mind.
Thanks again.RY
