Question 1:
Does anyone know what this very small diameter vacuum line is coming out of the wiring harness by drivers side firewall?
My 1995 car has the secondary air injection system removed as well as the heating blower, which I suspect it goes to and is
no longer needed? See picture.

Question 2:
Are fatigue cracks common in 911 engine fans? I have spotted a few cracks at the root of the blade that look deeper than just coating.
