      The P0440/P0441 aren't necessarily evaporative system leak codes. Your gas cap is probably fine,
      The 'general evap system failure' and 'incorrect purge flow' for me have usually been a failed NVLD switch.
      Mopar calls it a 'detector', but please continue with your diagnosis to confirm the problem.
      Am I correct that, if the gas cap was indeed loose, then tightened, the fuel tank had to reach full, then below 1/4 before clearing??
