look at it closley
my vacume comes out of the carb,down around the EXHAUST manifold then back up into the carb.Is this what you are talking about?I could be wrong but I know it wraps around the exhaust and comes back in.My mind is frazzeled working on a 91 camaro my daughter left me to fix while she went to college.Anyone elese rowing the same boat?Logan have fun by the time you blink your eyes you will wish they were 5 years old again.
