What is the purpose of this canister? I pulled the front bumper off today to take some measurements, I noticed the canister is cracked. I don't know if it happened when I was taking the bumper off, or if it's been cracked for a while.
Is it needed to run the vehicle or can I delete it?

Vacuum canister sounds like

 

Diffinately vacuum canister. I cracked mine once and wrapped it tightly in electrical tape but re located it to my engine bay

 

Do I need it ?

 

For cruise and hvac selector at least

 

I assume that means it controls the air conditioning. Mine is not working and unplugged.
I'm going to gut the whole air conditioning system anyway.

 

I think it's the blend door that's vacuum operated. Besides that and cruise I'm not sure if it controls anything else

 

Isn't it for emissions?

 

I'm going to try just plugging it off, I don't have air and can do without cruise.

 

Your heat will only work on defrost without it

 

Maybe you should do the electrical tape trick....

 

I taped mine right around the center where it went together from the factory. Electrical tape worked and I drove it like that for almost a year

 

Here ya go.

 

I'm going to build a bumper and add a winch, I guess I'll have to find somewhere to stick it after I fix the crack.
Mine is shaped more like a blimp.
I could never understand how you store vacuum???

 

With a diaphragm and a one-way valve.

Are you going to have cruise control?

Mount it to /near the passenger side firewall/inner fender within 12" of your vacuum lines.....
