Cannot fill fuel tank more than 1/2 full. This has been an ongoing problem since beginning of ownership. 4 trips to the dealership including tank, filler neck & sender replacement has not resolved the problem. As an experienced auto technician of 27 years I inspected the design of the fuel tank and determined that the "saddlebag" design is flawed at the top and center, where that section is only about 5 mm thick and is higher than the top left and right sides, not allowing fuel to flow into the righthand side. I have an appoint with the Ford dealership in ft pierce on Monday, November 19th, 2007. At that time I intend to relay my opinion on this matter, however I'm not expecting a satisfactory answer from them.
: the contact stated while putting fuel in the vehicle the fuel nozzle must be held in a certain position to obtain a correct reading from the fuel gauge. Before putting fuel into the vehicle the fuel gauge read half a tank, while attempting to put fuel into the vehicle it showed full. The vehicle was taken to the dealership, they replaced the storage tank. However, this did not correct the problem.
