Thread: Where is the vacuum line??

I am going to be putting seafoam in my car and I know 1/3 of the bottle goes if the vacuum line from the brake booster but I am unsure where that is located. Pictures would be great so i can see exactly where it is. I have also read that you can put it in the intake, I assume they mean the air intake, and I am unsure if that is such a good idea because I can easily do that because i can just take the filter off my cold air intake and pour it in that way.And if I do pour it in my intake than should I do it while its running? please help anyway you can thanks!

leave the car run. and pull the line coming out of the brake booster. its the black round thing behind the master cylinder. easy way to put it is, its right in front of the steering wheel on the other side of the firewall. there will be a line on it. pull it out. car will start to run like crap, then you just stick in in the seafoam can and let it stuck it out.
