4th gen gas tank install using TPI
 

So, I have the wiring sorted from the tank to the car, I have the sender squared away, the fuel supply and return lines are done. The charcoal canister on the 2002 fuel tank is still there and I will let it vent to the 4th gen canister. The part where I am lost is, what do I do about the charcoal canister/evap purge etc from the car? I'm assuming the ECM will freak out and set a code if there is no purge event?
