SR IACV vacuum lineq

[Adam496]

Where are you guys getting the 3/4" vac line that runs from the iacv to the nipple on the cold pipe? I've pretty much tried every auto parts store in the area with no luck. I can get heater hose in that size but i am assuming it would collapse under the vac. Is my best bet oem?

heater hose would probably work fine. that hose doesn't get vacuum, because it is attatched to the intake before the throttle plate.
