Cruise Control Vacuum Line Routing

Post by Stu70 » Mon Dec 09, 2019 6:41 pm

Retro fitting cruise control into the car - will soon be the heaviest underpowered car around.
I just need a kind person to maybe snap some pics (or paint a 1000 words) with the routing of the vac line from the pump, around the bay to where (?) it enters through the firewall. I’m hoping to remain as factory as possible. I’m also thinking factory was that plastic small OD vac line...
Many thanks

I’ve looked and looked...

To be clear - I’m after the physical path the hose takes as it transverses the bay and through the fire wall ie which nipple on which rubber ended conduit it passes through. I don’t want to just cable tie a hose on to random parts and lines.

I’ve got the engine pulled on the 1998 but sonic may have already grabbed that stuff, I’ll look later this week, on travel, unless I can squeeze it in this morning

Absolutely fantastic ! Once again you’ve gone above and beyond. Many thanks Abscate. Gold star on the fridge for you 👍🏻
It follows the same path via a few more tabs across the fire wall on the RHD models.

Stu, aren’t you guys RHD?

It might mirror but it might not.

Yes we are RHD, me not putting down in words what’s in my head. I was able to run the solid plastic line up behind the throttle cable , but wanted to see how it snakes up the chassis and to which conduit it penetrates the fire wall.Now Im not even sure on the RHD if it runs inside the engine bay or inside across under the dash.
Wow, You guys have it hard with the booster on that side all squeezed in there behind the abs :shock:

But it’s all in now and it works, yay.

It looks bad but I remember there are some nasty operations on RHD that we don’t get the pleasure of doing. I bet Mike knows some of these. Brake booster removal might be one.
