Is this approx the same set up on non-turbo 16v (89)? I believe the 2nd hose the previous post refers to develops vacuum under idle/non-acceleration - I believe this because the hose on my 89 16v is slightly saturated with something, develops a whistle after engine is warm and under idle/non-accel - I believe vacuum is causing whistle. Local shop told me to replace it with 3/16" fuel line that is resistant to softening with contact with petroleum
