The computer shows Gas cup air leak. It looked still in good shape but replaced the cup with a $32 new one, still same problem persists. What are the next troubleshooting steps?

My mechanic already reset the computer, but still the same signal"gas cup air leak"came back.
What can I do next? and any idea of costs?

You will need to get the EVAP system tested. There may be a major air leak. Maybe one of the hoses or the filler tube is damaged.
