Stuff that can/will break when replacing vacuum lines?

[EdWindows]

I plan on replacing all my vacuum lines while I install my phenolic spacers, and was wondering what little pieces have plastic connectors that easily break?
I figured I can order them all and just return what I don't need.

I assume the following from this diagram will break:

• 1
• 2
• 5
• 7
• 8
• 10
• 11
• 12

Can anyone confirm this? I know for a fact that 10 is very likely to break and is the most expensive of all as most threads I've found on this subject talk about that solenoid breaking.

Also, part numbers would be very helpful as I cannot find a diagram of the underside of the intake manifold on SubaruParts.com or my local dealership catalog.

Thanks in advance!
