broke vacuum line to air pump - advice needed
So I was changing out the alternator, which of course the alternator bushing is completely seized and I started moving things out of the way and accidentally snapped the very old, most likely now 19 year old vacuum line. I believe it is one going to the air pump. Perhaps item #28 or #30 in the diagram below.
I was thinking since it's just vacuum air line to get a universal one to replace it so I don't have to go pay porsche tax. Has anyone does this before? curious about success and also dimensions of tubing.
It is the black shiny hard plastic line this guy is pointing to in a different post

The best solution is to replace ALL of the vacuum lines in the system with silicone tubing. The rest of the OEM lines are bound to fail and trying to track down leaks is a real PITA.

The 996 or any Porsche for that matter, if we could get all the irritating little plastic bits replaced with steel or aluminum quality components.

I just spent 3 hrs (worked slowly) replacing all the lines, check valve, vacuum reservoir and change over valve for air injection. I had a minor idle flutter from a vacuum leak and since the parts where reasonably priced i figured i would just replace all of it.
Take out both center crossover intakes (have to take the rear intake to access the intake resonance flap acutator) , alternator (the vacuum reservoir is behind it in the middle of engine) and you'll have access to entire vacuum line system. All the vacuum lines where so brittle that they snapped apart when i was taking them apart.
I used this diagram which was very helpful.
The hardest part was taking out and reinstalling the alternator.

Just replace them all OEM and not worry for another 15 years...
