im trying to use "seafoam" on my 97 tahoe 4dr. i read alot of the forums and it says that your suppose to pour some into the brakebooster or vacuum line. Where exactly is that?

there is a big black hose behind your master cylinder that goes to that black round thing called the brake booster(just did it not to long ago)
