I've had my 93 Z32 TT in the garage all winter with a blown turbo. Due to financial and personal reasons, I haven't been able to finish the turbo swap until now, but I have the new turbos mounted and ready to go. My only concern at this point is this hose; it was pretty worn and cracked, so I pulled it off to replace it, except I can't find a replacement hose:

* Is this a special hose? If so, does anyone have a part number to order it?
* If it's just a regular vacuum line, what size? I can't get 3/8" line over the valve (the one that threads into the plenum), and any larger line will have problems with the hard piping on the other end.
* Is the driver's side line the same as this one? (it looks like regular line to me, but I haven't pulled it off yet)

Thanks in advance.

It's just a coolant hose so any fuel line will work.

Any idea what size? The valve and the piping appear to have different diameters.

It looks like it is part of the PCV system.

These guys are selling it for $18
Another option: unthread that piece, runs down to the hardware store and find a threaded ( probably brass) part with a smaller diameter nipple so you don't need to buy an $18 formed hose.

Or, unthread it and see if you can force it on with the piece off the plenum the rethread it in before connecting the other end.

Ha ha my bad I was looking at the turbo coolant hose. Not the missig one. He is correct pcv, any automotive hose should work. I think I used 5/8 heater hose for my car...
