If I wanted to run seafoam through a vacuum line which line should I use on this car? To be honest I am not even sure if there is a vacuum line that can be used to do this on these vehicles.

 

Pull the one connecting to the brake booster. I used it myself. It runs from the front of the Throttle body to the brake booster and is held in place with a spring clip.

When you do it, you cannot just stick it in and let it suck. It will kill the running engine. Just let it suck a little at a time.

Just remember to hook it back up.......

 

Doesn't kill mine, but I use a smaller vac line.

 

Which explains why it doesn't kill yours. I use the brake booster line because it is connected straight into the intake.

 

All vacuum lines are connected to the intake manifold. The one line to the throttle body still draws in air from the vacuum effect under the throttle plate.
