Can somebody verify the 1/8" statement. I'm at my local Kragen's and the only 1/8" tubing they offer is "fuel line". It's clear and looks significantly smaller then the hose in the photo.
Just be extremely careful you don't put any force on the stock electronic boost control nipple you're working with here. it is fragile and easily broken. Suggest you undo the spring clip and cut the hose along the nipple's axis, with a really sharp knife, so you don't risk snapping it off.
