carbon canister/emissions related

["sujit roy" <sujitroy@hotmail.com>]

What is the purpose of the carbon canister? I have three pipes going into my 
canister, I've seen two pipe versions.  Is there much of a difference?
Can I remove it, along with the other related stuff for emission controls of 
my CA,'71 Stag.
Do other Triumph of the same vintage have an extra gas tank in the trunk 
related to the emissions?  If I can remove the tank without affecting the 
performance of the car, what pipes do I direct where?
