2015 Ford F-150 ? The 23 Gallon Tank That Holds 33+ Gallons

Sitting at my hometown Shell in Gurnee, IL with the 2015 Ford F-150 after spending over 2 hours to top it off for the calibration drive... I drove about 18 miles incl. the photo shoot location before arriving at this Shell. When I began the fill, first click came at about. 9 gallons as expected. I pulled out the fuel filler spout from the truck and began the ordeal. I added 5.410 gallons at a rate of 0.004 and 0.006 gallons at a click for over an hour. At that point I stopped and went inside for a break. It is in the mid 20s here right now and falling so you can understand why. After 5 minutes I went back out for another hour plus and added another 4.649 gallons...
