Tank Filler Pipe And Cap problems of the 2001 Ford Expedition

After 3 service visits, I still have a fueling problem with my 2001 Ford Expedition. I demonstrate the problem to a Ford representative. As demonstrated, we started filling the fuel tank. After 9. 4 gallons, the nozzle automatically clicked off, we continued to fuel the tank over the next 10 15 minutes, with near continuous clicking off of the nozzle. At about 15 gallons, the Ford rep was uncomfortable with further fueling. I continued to 18. 6 gallons, whereupon the fuel finally rose to the filler neck and even spilled over a bit. I have found this is the only way to completely fill the tank. The Ford rep explained to me, very courteously, that once the nozzle clicks off a couple of times, the tank is considered full by Ford measures. The problem with this is that by that measure, I am reducing my fuel capacity by about 9 gallons, and at highway mileage of 20 mpg, reducing my cruising range by 180 miles. It is unacceptable to tell me I have to refuel my Expedition 180 miles shy of where I should be able to cruise and refuel. This is my fourth Ford auto in 4 years. I have never had this problem before. I am requesting that Ford remove the idiotically designed fuel tank in my Expedition, and replace it with a regular idiot-proof fuel tank. Fueling a car should not be rocket science.
