Our's is an 01, LX, with the charcoal canister in the engine bay (not in the back above the spare). This mod is definitely more applicable to those model years with charcoal canister in the front, though it could easily be adapted for the later years with the canister in the rear.
I have an aux fuel tank in our hundy - and its a gravity fed aux tank from Front Runner. It sits in the area above the spare tire hoist. Because of this, it is very easy to flood the charcoal canister since the new "full level" of the gas tank is above the outlet from the stock gas tank to the charcoal canister. Any downhill angle and fuel can flow from the tank right into the canister. So mine has been flooded several times. Also it was not allowing the tanks to vent so I had a bad fuel pressure problem - bad as in vapor and fuel spewing from the filler cap when opened after altitude changes
I found this canister on Amazon for $60 and used it instead of the OEM one ($600). The AC Delco one only has three connections, while the Toyota one has 4. The difference is that Toyota uses a clean air intake (from the intake plenum, after the air filter) vs. the AC Delco which uses the same outlet for fresh air and venting. Toyota separates the intake from the vent.
Mounting was super easy using some fat AC duct zip-ties and the original metal cradle. The OEM canister slides into this cradle, and there is metal spring tab you have to lever out of the way to allow the canister to slide up. There's a single bolt on the right of the picture below that needs to be removed too.
