Both these codes do refer to a large vacuum leak in the evap system , so with what you have done so far the next step is to run a diagnostic scan on the system and or do a smoke test to look for that leak. In some cases if no leak is detected with the smoke test it will be an internal leak in the itself. You can also check the filler neck and adjoining tubes to the fuel tank for any leaks or loose clamps.

so bad typing, as I was about to say usually it is the charcol canister thatmay have an internal leak if the smoke test shows negative, but if the scanner is used it will locate it as it does an active test on the system.
