These lines run by the steer knuckle. There is two of them side by side, one like I said runs down and over and the other one was sticking up, but it may of went down to and connected some where, but I can't figure out where. I am utterly confused as to where it goes. It feels like it has suction to it, and like I said my ABS is randomly acting up on me, giving me network communication errors to the rear speed sensor, and I just replaced it yesterday to make sure that wasn't it, and still every once in awhile getting the same random ABS issue. Its got to be related to the vacuum leak.
