There is a canistor under the duct work for the air cleaner on my car. Is this a vacumn canistor? Can anyone tell me more about it?

 

ithink you arefeering to the charcoal cannister. if thats it, its used to absorb gas fumes. i may be wrong as that stuff is gone from my car.

 

Ahh ok. What benefits are there to removing that? How do I do it?

 

all it does is keep fumes from exiting the car, just plug the hoses . no benefits , just looks. verify with someone that knows that lives by you to be sure we're talking about the right part, don't want to mess up your ride.

 

I'll take a pic of it monday and post it.

 

If indeed it is the charcoal canister, it also provides the vent to the fuel tank. Just plugging the lines will produce a vacuum in the tank as fuel is pumped out. End result - no fuel flow.

 

my fuel tank has its own vent , back by the rear seat. sometimes its hard to give advice half a continent away

 

It's part of the EVAP system. You wight as well just keep it. Back before EVAP systems, fuel tanks just vented a ton of HC's into the atmosphere. Now the systems are sealed and the vapor that normally was vented is instead purged into the motor to be burned.
