Topic: 1967 Power Brake Booster Hoses

[196667Bob]

I am adding Power Brakes to my '67 Convertible. I have an NOS Booster, check valve, pedal support, new master Cylinder, etc.  As I don't currently have PB on the car, the vacuum line to the C4 transmission modulator valve goes from the fitting on the intake manifold to a steel tube from the modulator. With PB, a hose goes from the Booster Check Valve to the intake manifold, and another hose goes from the Check Valve to the steel tube from the modulator.

I have the ID, OD and length of the hose from the Booster Valve to the intake, but not for the hose from the Check Valve to the steel tube from the modulator.

Could someone be kind enough to furnish me the ID, OD and length of that hose ? Also, were there any markings of note on said hose (note that on the attached picture of my existing hose from the intake manifold to the steel tube from the modulator, it has a white stripe. My car is a January 31, 1967 Dearborn Build.

Thanks for the help.

Bob I do not believe that the modulator line comes off the booster check valve. I think it should come off a different fitting on the vacuum tree. If you have the 67 Ford Vacuum service manual check the diagram there. I'll check if I have a picture.

Marty,

The 1967 ones I own/ have owned do come off the booster.

Marty : I was going to mention that John (67gta289) had first furnished me the information that his 67 had Factory PB, and that is where the hose to the AT came from (he beat me to the draw).  While John's is a SJ build, and has the Thermactor, and mine is a Dearborn build with no Thermactor (and no vacuum tree), there is a possibility that it could be different.
The 67 Vacuum Manual does not show the Mustang lines with PB Booster; however, it does show it for 289 Falcons and Fairlanes. I have not found any help in any of the MPC's either in diagrams or text in regard to the hoses. However, in looking at the aforementioned Falcon/ Fairlane Vacuum Diagram, the 67 Shop Manual, and the Chassis Assembly Manual, I think that all indications confirm what John noted; that the vacuum line to the transmission goes from the PB Booster directly to the transmission.

That being said, I still am in need of the specs on that hose.

Thanks for the input.

Can confirm the somewhat odd routing for the automatic transmission vacuum source for San Jose cars equipped as listed above.

Should be able to provide pictures of allot of this but it will not help with the specific measurements needed. And, unfortunately, not planning on taking a yard visit in the near future. If it doesn't rain this weekend might get lucky at the Turlock swap meet though it looks like rain

Jeff : Thanks. One would sure think that there would be someone "out there" that had an early Dearborn 67 C Code with AT and PB (no A/C, Tilt or TE), that could do some quick measurements, wouldn't you ?

Did a 67 power brake rubber line have markings on them IIRC such as the ones sold by Dead nuts on for 68 and later years.

Would guess that there would need to be identifiers on them to identify which supplier, batch and or date. Don't believe they were ribbed for identification purposes like the radiator and by pass hoses

Will look through the 67 pictures but guessing its not going to show much with the dirt, dust and other build ups

Since its a Dearborn car might reach out to the Cougar guys - just tossing out a bigger net Challenge I'm finding is that power brakes were sort fo a new thing in 67 on these little cars making that option not a popular one

The rubber line from the intake manifold to the booster did not based on my experience and information.  The subject hose of this thread, from the booster to the automatic transmission modulator valve is what Bob is asking about.   

[196667Bob]

Just for info : the rubber hose (which I believe to be original) from the intake manifold to the steel tube from the transmission modulator on my currently non- PB 289, has a white stripe on it as shown in the picture attached to my original Post.

Thanks for the clarification. We seem to often need to get reminded as the threads meander a bit

Agree those small dia hoses normally don't have printing though sometimes there can be ribbing

My bad, I read the OP and saw booster hose, something Im working on and lost focus.

[ruppstang]

Here is the routing for the vacuum lines on my 11-04-66 SJ convertible. This is how it was when I got it, a PO could have changed it but I doubt it.

I have seen the small vacuum line in bulk from Ford with that white stripe on it but do not think it was assembly line.

 I am not aware that the large hose that supplies the booster had any marks.

Dead nuts has a reproduction hose for 68 and up, it has 'Gates' hose markings and a date I thought the 67 may be similar.

Believe the difference is in the way the car is equipped
