Using Seafoam Through a Vacuum Line... Which One Should Be Used?
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.
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.
