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.

Starter Solenoid replacement-how difficult? Where to buy?

Posted by Norman Silverman on August 20, 2019 at 8:24pm 6 Comments

Hello All.

I believe the starter solenoid has gone bad in my 64 DeVille. When I turn the key, often all I get is a click, then if I try a few times again the starter turns perfectly. All battery cables are on tight and the battery is good. So, I believe this problem is the solenoid. Where do I buy the right solenoid and is it necessary to remove the starter in order to swap it out? …

Upper A Arm Rubber Bumpers

Posted by Gene McIlroy on August 12, 2019 at 1:30pm 3 Comments

I have found a very good replacement part for the Upper A Arm Bumpers.  The top part is identical to the originals the bottom can be used as is or after a few minutes with a belt sander can be ground to the V shape as the originals were.  The replacement bumpers are for a 2001 to 2005 S10 Sanoma or Blazer.  Part number is on the box in the photos.  First photo is the box next to the box is the S10 part and an original.  Next photo shows my sanded down part next to an original.…
