i put my exhaust mani back in yesterday... and i see a peice of hose just sittin there.. I took it off to better reach teh bolts. I was just wondering what it was for... i have no PS, or AC... and i have some emissions removed, at least the egr...
here's a pic:


The circled part, will that cause a vac leak meaning i need to cap it off or is it fine if i left it alone... like i said there was a short piece of hose, about three inches long just sittin there before, not connected to anything...
