There is a tall hex shaped adapter screwed into the intake with a nipple coming off it for a vacuum hose, I think.
I will try to get a picture.
The truck did have cruise controll..could it have been attached to that?
Thanks again.  |
Typically that is used for transmission vacuum but it also gets used for power brakes too.
On a high performance engine that pulls minimal vacuum you can actually lean out the #8 cylinder by plumbing power brakes to it.
Run the power brakes from the port on the throttle body.
