Why can't I fill up my 06 Corvette more then half way - better answer?

The answer to the previous posting of the same question did not work for me or my neighbor. Since that question is closed for answers, I'm re-posting the question along with the answer: What fixed the problem of our Corvette gas tanks not filling past half way was to replace the solenoid (part #20761332)
