Fuel Tank capacity issue

I have noticed that I can put more gas in after it initially shuts off but still not able to get close to the 17 gallon max capacity. If you are averaging 25 miles per gallon and when you fill up it is saying 350 until empty...that would be 14 gallons. I just took a road trip and the fuel economy of the Hybrid Max was only 22 MPG and my average speed was 78 MPH. This does not get anywhere close to the MPG they claim.
Toyota has told me it is bad to keep adding fuel after the pump shuts off.
