Title: Source for vacuum lines
Post by: 6262 on October 02, 2018, 06:59:44 AM
I would like to replace all the vacuum lines in the car. Mine are a mess... I have no power trunk and locks.

They were color-keyed originally, as far as I know. What was the original diameter? I have different sizes and materials, but they appear to be makeshift solutions by previous owners.

Is there a source for a set? Another good source, where I can find the correct material? What is the correct material?

Thanks in advance!

Are you inquiring about the rubber or metal vacuum lines?

It is probably a foolish question... Where on the car are the metal vacuum lines? Vacuum advance, right? But somewhere else?

Vacuum advance and Idle Speed-Up lines for those with Air Conditioning. So you still didn't say which...rubber or metal?

You are right... I did not think of the idle speed-up.

I need the rubber lines.

Inline Tube seems to have color coded sets, but I have heard the quality of the color coding leaves something to be desired. 

That said, you can get generic black rolls, put some paint down on a cookie sheet, roll up the hose, and roll the hose through the paint.  This will give you a nice painted stripe.

Thanks, Dan.

I did not find anything on inlinetube.com .

But I have found a set at Caddy Daddy

and another at USA Parts Supply.

Both describe the product with meager words. But for 30 Dollar one could give it a try. However I wonder what is the correct diameter? USA Parts Supply does not specifiy it for the set but offers an assortment of different diameters just below the set... On my car a wild mish-mash of hoses can be found, probably whatever was at hand here in Germany. The Master Parts List is also of little help.

I found something very interesting at a Pontiac Vendor: Do you think 5/32" is the correct diameter?

There are actually multiple diameters.

What vacuum options do you have.

@Clewisiii  None, with the exception of the A/C.

Here are images from some of my interior vacuum lines. 

The large diameter is marked red. However the AC line on mine is a small diameter red.

Great help as alway, @Clewisiii . Thank you!

What are the exact diameters?

Ok. I have a few sizes for you.  These are the three

Larger line in Cab
Small line in Cab
Smaller line on AC vacuum diaphragms

3/16
1/8
9/64

Here is a picture of the difference of the 1/8 in Cab to the 9/64 on the AC box

This is not a comprehensive size list. But it is what I can offer.
