99 TJ tiny vacuum lines

While I was putting on a header after removing my second OEM exhaust manifold I cracked a tiny vacuum line that comes off manifold head towards a little black box by the brake system. I dont even know what it does let alone try to find a repair part. Any help on repairing the line/part number? fabricated lines? is this air control? There is another one that heads toward the passenger side of vehicle along the firewall. Theyre so brittle that i know theyre going to crack open again.

The easiest repair to do for now would be to put a piece of small diameter electrical shrink tube over the broken plastic tube a carefully shrink it up, it will not only solve the leak problem but it will hold the tubes together until you get new hoses.

Most likely the line to your cruise control. The other lines are for the climate control doors in the cab that switch heat from floor to windshield and so on.

If you goto a parts store you can get a small piece of vacuum hose to splice the two ends back.


Be sure and tell them you need the rubber type, or they will try to sell you the plastic type which wont work

Ahh the cruise control.
i did use elect. tape temporarily but how do i find new hose/tubing. I like the idea about the rubber hose splice.
If i get all new hoses from an auto parts store how do i get these special fittings on it?

+1. I just did that to fix one I broke on my truck. I had some left over.
