I have a new gas cap and tested the valve under the hood and it's good (pulled the hose coming from the tank and the valve started going thump thump thump after a few minutes of engine running).

Is there another valve somewhere? Does the charcoal canister have separate parts that can be replaced individually?

Assuming I don't have a torn hose or rodent damage at the top of the tank (will visually inspect soon).

I also have P0171 and P0174 which makes me fear the rodent damage.
