I've been replacing the vacuum hoses and have found and fixed one leak (pipe under o/s TB was holed), but I'm sure I can hear a hissing from the area in the attached pic. Is the circled pipe a normal vac pipe which I can remove and replace, or are there any other vac lines below this one that might be causing the hiss?
