Can anyone tell me where to locate the brake booster line in a 99 civ? im attempting to seafoam it and i cant seem to find it....pics would be great too

 

It's the one the dudes holding

 

alright cool

now ive been searching around about the places where seafoam can go. can it be either the brake booster or pcv valve?

 

use the vacum line from the fuel pressure regulator to add see foam

 

I had always used the FPR line as Mitch mentioned, but saw a few people posting about the brake booster line in my search for the picture above. I don't think it matters a whole lot, as long as the line you're using is taking air towards the motor.
