The fuel tank is a sealed system; i.e. pressurized cap w/ vapor canister - for as others have said - EPA regs.
The charcoal canister collects vapors from the fuel tank, and then - via vacuum (check valve at canister) - routes them through the intake manifold to be burned
My only caution about removing it completely - and I've heard urban legends about garage fires - is - those vapors need to have
someplace to go.
So, personally - I don't see a problem - and out of abundance of caution - with keeping the canister - even though it tends to be in the way of the cold air intake.
Maybe someone else has better details of what they do for a canister delete.
