01 Sub EVAC cracked

Hi, Need a little help. The "Service Engine" lite came on in my 01 Sub. Took it to the dealer and they say a tube on the EVAC canister is cracked. The only way to fix it is to replace the whole canister and they want almost $500 to do it. Was wondering if its something I can replace myself, and can anyone tell me where it is ( I assume its in the engine compartment somewhere) and what it looks like?
Thanks in advance for the help.:banghead:

Ok- I think I found it- I was way off. Is it the black capsule/container on the back of the gas tank?
Can someone please confirm?

The EVAP caniste is in front of the gas tank, large square box with lines going to it

Thanks, I found it.

There was a recall on the 01 evap canister or system about 8-9 months ago. I don't remember what the problem was but they fixed mine with 200k miles on it.
