    Hello all,

    I'm working with a 2002 Ram 1500 SLT 5.9L 360

    I need some help identifying a broken line coming out of the "T" junction that connects to the break booster check valve.

    It seemed to go somewhere into the top of the engine bay just above the throttle body (I noticed the line snap when I was reinstalling the air cleaner) but I cannot seem to identify the line or where it goes and whether it is safe to use the truck in the meantime.

    Help is very appreciated :)

    Where exactly does the other small black vacuum line attach to? The one going straight down from the "T"

    Is this truck 4WD?

    Yes, it is a 4WD. The line that goes straight down from the T seems to go into this unit (attached picture) that sits under the battery.

    That unit you are referring to is the cruise control.

    Check the vacuum ports on the side of the intake manifold below the throttle body. There are a couple of ports on the kegger manifolds.
