yes you can remove it BUT you will leave your fuel tank vented to the open air ,letting fuel evaporate,creating a possible fire hazzard,losing milage due to the fumes not being burned,if the check valve goes bad you could create a siphoning hazzard + if the car ever rolled over same thing
you could possibly save 2-3# tho doesnt seem worth the risk to me
If you remove the charcoal cannister, you need to plug the hole in the upper intake that it attaches to. There is also an eletcrical connection connecting it to the computer. I don't know it disconnecting it will throw codes or not. Also, you may smell gas fumes from time to time because they are not being contained and processed by the cannister.
The charcoal traps or absorbs the gas fumes from the tank instead of venting the fumes to the atmosphere. The ECM occasionally applies vacuum to the charcoal cannister and sucks the gas fumes from the charcoal into the intake to be burned.
