2004 Toyota Corolla Fuel Filler Neck Replacement, P0441, P0442, P0446 EVAP

Changing Fuel Filler Neck on 2004 Toyota Corolla. Vehicle was getting evaporative (EVAP) emissions codes DTC MIL P0441, P0442, P0446 EDIT: 4/28/2019 After having it successfully clear the codes and run all the monitors, now the car is back to a P0441 and P0442 error codes. I'll have to figure out what is happening. EDIT: 8/23/2019 This does seem to have fixed the problem. Initially, I had some error codes again after the repair. but it seems to be working now.
