|This hose has been discontinued. The one that was on my Z was a universal short silicone hose and fit and looked terrible.
My Z is a factory built 1990 Twin Turbo 2+0.
I found this hose on eBay for $13.00 including shipping, and the Hyundai dealerships still stock it for 10-15$.
I wanted to post this here for reference in case anyone ever needed to replace this hose as there is no silicone replacement and the OE is gone.
It is for a 2017 Hyundai Veloster. ( Hyundai 59130-2V300 Hose Assembly-Brake Booster Vacuum ) Inside diameter is the same 11/32 as OEM was. Clutch booster to check valve formed hose.
OEM 90-96 Z32 installed (example from web search not my photo)
HYUNDAI INSTALLED ON Z32

Im sure there are likely other hoses that would fit this task but this was pretty dang close and super inexpensive. Clamps are included on the hose and fit excellent.
