Question Stuff that can/will break when replacing vacuum lines?

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!

The iris valve is about all that breaks if done properly and carefully. Also, all of the parts will be special order and therefore non-returnable, or will be a 10-25% restocking fee depending on your local dealership.

Just a thought, I have had very good success fixing broken plastic things with Epoxy Putty, if you do break off a nipple you may want to give it try. This is the product that I have.

Please refer to the scans I put together of the entire USDM parts catalog.

The thread (link below) that has all of the information has been made a sticky a little while ago to stay at the top of the "General SVX Babble" section of this forum.

All part numbers with diagrams for US SVX cars from 1992-1997 can be found in these scans.

Also.. the attached jpg is a summary:

OK, good to know. The IRIS valve is that little check valve marked as #8, right? And OT sells it on his site?

Awesome! I didn't know of such a product. I'll go buy some before I pull off my manifold.

Thanks for the link to the thread! I found that chart earlier in the Vacuum Line Replacement PDF in Icing's torrent, but it didn't list any of the solenoid or check valve part numbers.
