Why does your Cadillac Escalade of pressure in the gas tank?

If your Cadillac Escalade is experiencing pressure in the gas tank, it could be due to a faulty fuel cap or a problem with the evaporative emissions control system (EVAP). A damaged or loose fuel cap can fail to seal properly, allowing pressure to build up. Additionally, issues with components like the charcoal canister or purge valve can lead to excessive pressure. It's advisable to have the fuel system inspected by a professional to identify and resolve the issue.
