Chrysler Town & Country vapor leak from gas tank issue, gas tank replaced twice on Chrysler Town & Country

Some Chrysler Town & Country owners report experiencing persistent vapor leak issues from the gas tank, even after replacing the tank twice. These problems may stem from a clogged charcoal canister, which can hinder air escape during refueling. Additionally, a loose gas cap is a common cause of a P0456 code, indicating a small evaporative leak. Owners also note that failure of the vapor/liquid separator valve at the top of the fuel tank can allow liquid fuel to enter the emissions system, potentially flooding the charcoal canister. Furthermore, issues with the fuel pump or fuel sensor assembly inside the tank, including gasket failures, could contribute to the ongoing leak. To effectively resolve these vapor leak issues, it is crucial for owners to ensure that all components of the evaporative emissions system are functioning properly.
