Question about 1995 Pontiac Bonneville
This is the power brake booster vacuum line, the little round thing is a vapor separator to keep gas from entering the brake booster and destroying the rubber diaphragm, the line goes to the intake manifold near the rear of the manifold, the length of the vacuum line is a good guide to where it hooks up, if you run the engine you will hear a very loud vacuum leak to say the least.
