Does anyone have a part number for the vacuum fitting at the back of the carburetor? It has a male end for the carb, a female fitting for the transmission vacuum line, and a hose fitting for the vacuum tank. I've been to nearly every auto parts store in Brisbane and haven't seen anything remotely similar.

Year, model of car and carburetor?

From my 1964 shop manual, page 13-21:

From my master parts book (64-74) I have found this:

I do think that 1486305 will be the correct one, but not sure as its stated as 1966:

Hope this can help you.


I have one on hand for you. I need to clean it up, but its a good piece.

Send me an email to;

1964 with a Carter carb. This is the fitting, the female socket that the vacuum modulator line screws into is stripped out.

Ricky, Your illustrations are pointed to the fitting on back of intake not on the carb. The intake fitting feeds vacuum in side cab for AC/Heat and Neutral safety switch, and over to the door lock/trunk release canister. The fitting on the back of the carb is like the one in your picture that feeds the power brake booster via the large nipple and the transmission line via the threaded connector. I have a dozen or so of these and can pick out a  nice one for $5 + s/h. Shoot me an email if interested.

Was not Rickys pictures. I posted them in response to his first post.

Yes sorry, my description was incorrect, it connects to the Brake Booster and the Transmission Vacuum Modulator.

A picture is better than....

You may be able to use the white plumers tape or you can JB weld the parts together depending on how badly the stripped threads are


Yeah my plan was to use thread tape on the stripped out fitting in the short term and tape it up tight. It's only temporary until I get a new fitting. 

Only use the slow dry JB weld ( 6 hr dry )

Have been looking into these vacuum connections on my car and as I have a 4-speed Hydra-Matic its slightly different.

Have one 3-way connection on the engine (red circle) and one connection (yellow) on the carburetor.

From the carburetor the vacuum is applied to the brake booster. 

From the connection on the engine it goes into the dash via the green marked hose. To the vacuum tank via the blue hose and to the gear box vacuum diaphragm via purple.

The t-piece that is displayed on Rickys picture is not fitted on my Series 62. I guess it's only fitted on cars with 3 -speed Turbo Hydra-Matic gearboxes.

Specific vacuum hose setup depends on model year, AC or no ac, optional vacuum power trunk and power door locks, and on 64 THM or HM transmission. There are a lot of variations.

63 guidematic issues

Posted by maurice lapoiinte on November 24, 2019 at 3:10pm 0 Comments

 So my 63 guide matic headlamps stay on low beam all the time. I have so far bypassed the system and everything works normal. I have been thru the trouble shooting in the manual but this is where the confusion begins.on my car when the power relay is powered I have low beam and when its not powered I have highbeam, this appears to be opposite what the diagnosis says should be correct.The wiring is all original and no wires have been mixed up.has anyone ever unplugged the 2 wire connector…


Another advantage of the Pertronix III

   Having tried both the II and III I can say the multispark feature of the III offers a smoother idle . It is also easier to install .Does not require removal of the distributor

Stuck at two red (dash) lights!

I hope someone can help solve these two electrical problems that appeared one after the other.

By way of background: The car, a '64 Eldorado has very limited use. It was at a restoration shop for 15 months until last January-  that supposedly did a bunch of wiring repairs including rebuilding the gas gauge that still hasn't worked properly, and the clock that hasn't worked, and re-soldering the broken wires in the drive door. All window and seat controls appear to be…
