I took off my stock bumper recently and saw this behind it. I have no clue what it is for. Any ideas?

 

Its a vacuum something or the other however taking it off and putting a bolt in the cord is a quick remedy as it doesn't really serve a purpose. I ripped mine off with a crow bar when i trimmed my stock bumper, ha!

 

Vacuum canister. You can relocate it or cap it off like already stated.

 

Thanks! I appreciate it.

 

Only issue is, you cap the line and the heater doors won't work. I think it defaults to defrost.

 

Don't plug it just relocate it you ne3ed it working, if in a hurry use a plastic wire tie that's what I did 4 yrs ago on mine. Its still on there with the tie holding it lol.

 

lol this.

Dont just plug it. Thats the worst advice. Read up on it. Ppl usually just relocate it to the engine bay. Thats what i did

 

What exactly does it do? And is there just air inside?

 

It's a vacuum reserve canister. It holds vacuum.

 

The Jeep Egg is a vacuum reservoir. When under heavy throttle, the engine's vacuum is reduced (something to do with air going through an open hole, if you can believe that).

The vacuum reservoir continues to provide vacuum to the HVAC and cruise control system when going up hills etc.

 

you beat me too it
