Evap Canister Location

I am getting a PO456 code. I changed the gas cap even though the "old" one was barely over a year old. Reset the code and all was well for about 3 days. I've been reading posts about this code and it sounds like I need to check the lines going to my evap canister for cracks. I can't find the darn canister anywhere. Where should it be on a 2003 TJ Rubicon?

It's in the rear of the passenger side rear fender well. I believe you may have to remove the plastic inner fender well to get to it.

Yes. Rear passenger inner-fender well. Remove the fender lining and you will see it. Its a big PITA.

Check the rubber hoses in the system real good, don't just look at them and assume they are good. I would probably just change them out to make sure, then go from there.
