Before i chucked mine i put it under the hood but now i just run the vacum line on the end of the battery terminal bolt and junked the can.......

Here's the best pic i have......Hope this helps!!!

just take it off and put a bolt in the end of your vacum line. thats what i did

The vacuum ball serves no purpose other than to terminate the hose? Really? Cause I pulled my bumber endcaps off and it looks kinda ghetto with the bottle and horns hanging out there.

So all your heating vents still work like that? I was under the impression it wouldnt....

Why is the answer to every problem on here... "Just take it off. You don't need it."????

Q:"How do I adjust my e-brake?"
A:"Just take it off. You don't need it."

With that out of the way...

Vaccum ball relocation:
Many XJ owners relocate the ball under the hood. BUT not all of them are the perfect round type. Some are huge horse-pills. Makes it hard to find room under the hood when the engine compartments on many XJ's are tight on space.
Good relocation site: In front of the harmonic balancer. There is more than enough room and you will not hit it everytime you need to work on the engine.

The radiator support has a wide lip at the bottom that already has holes in it. Simply make a small mounting plate and attach it to the radiator support using stainless hardware. Then drill two holes and mount the vaccum ball.
Disconnect the vac. line alongside the BATT and use the end that was plugged into the ball, just run a short piece of hose to connect it into the system.

Here's what it could look like:




HORN(S): These are easily mounted near the vaccum ball or behind the grill. BUT make sure you do not block too much of the radiator as 4.0L run hot to begin with...don't need to make THAT problem worse.

The cannister serves as a holding tank to provide a negative atmosphere for your heating/cooling system and other items under wide open throttle conditions.

Its just a reserve ball. Its meant to store vacuum for your brakes/vacuum accessories. I would suppose for in a case where the engine died while you were you would have some stored vacuum to help you stop the truck. The previous owner of mine ziptied it to the radiator overflow bottle next to the engine. I may find where the line exits the engine and cap it instead of sticking a bolt in the end of the line.

Thanks Howler and radio flyer. That is more the answer I was looking for. Although taking it off is much easier...I would rather any possibly necessary items remain in my rig. I'll get me a steel plate and stick em under there.

I believe it helps engage the cruise control also if so equipped. Maybe the guys that get rid of them don't have cruise???

i have cruise. as long as you plug it after the cruise control it will still work

Your xj has an electronic motor for the cruise control, the older xj's used a vacuum motor to pull the throttle. If you pull a long hill that requires at or near WOT, you will find that your heating and cooling will default to defrost while under those conditions. Once you ease off the throttle, you will notice that your setting will return to wherever you had it-heat,vent,combo. This is a factory design that allows you to maintain a clear windshield in the event you lose vacuum that runs the doors in your HVAC system
