I'm trying to make sure I've got my lines correct. I have one vacuum line coming from under the dash through the firewall. It goes into a T with another line that comes from a port on the left of the wiper motor. Both of these lines ran to a hard line that connected to the fuel pump. Is this correct?


Also, does the line run through the 2 clamps on the firewall next to the heater box?


One more thing. There is a port on the top front of the wiper motor in the middle. I have nothing going to that. Is that correct?


Thanks!

I had to think for a minute as I was reading your text, because I always want to go from the source in, and your description went from the switch out, but your plumbing looks correct.

The port on the front of the motor is a vent. Nothing gets connected to it.

Cool. You just can't find this stuff on google images like you would want. Any help on the lines that run from the washer jar to the firewall by the heater core hoses under the dash? Mine were all broken and missing. I don't know what goes where. Thanks!

 

Gordon (Olds Dad) nailed this back in 2011 with this excellent drawing.

Here's his diagram, hope you can open it.

 

I found this image for the vaccuum line routing on a 56 Buick while searching for the same info on my 55 Olds. Hope it helps.

 

Dang, I can't open it! Is there somewhere else I can view this? I think its what I need.

That should do it.

 

Awesome thank you!

 

I believe that there is a vacuum buffer tank involved too?
