Hey guys, I removed my cruise control on my 91 5.0 mustang. The problem I am having is since I removed it I am getting a hissing sound when I depress the pedal, and when I press it all the way down its a constant hiss. I know its got to be related and that I probably have a vacum leak. What I did was the line that was going to the cruise control I reconnected it to the line that goes to the "tree." Connecting these to lines is a white tube that has a disc on it. Can anybody help me. Maybe I connected it wrong. Should I remove that disc thing, and just put a straight connector? Any info would be great-J
