I have to allow the gas to trickle very slowly into the tank while filling to prevent the nozzle from kicking off.  I just purchased the car and the tank was completely empty(yeah, dealer should have topped it off and did not). I tried two different pumps and both did the same thing.  When I stopped filling the tank I could hear the gas gurgling like there was an air bubble trapped in the tank.  Obviously this car is fuel injection and is a pressurized system so I do not believe there a vent off the tank. I assume that it has a line going to a charcoal cannister and am wondering if it vents through that and maybe there is a problem with the solenoid hooked to that system?
any help will be much appreciated..

There was the same problem with the early 2005 Mustang GT's.

The temporary fix was to turn the gas nosle to the 4'o-clock or 8'o-clock or generally tilt it to get it to fill the tank.

May work for you .....

Difficult to fill
Fill limiter vent valve stuck closed
Evaporative emission (EVAP) canister restricted
EVAP vent valve stuck closed
Restricted vapor lines
High reid vapor pressure or high fuel temperature
Fuel filler hose is pinched or kinked
Ignition switch ON, and the vent valve is closed

..or maybe a five ft long 1/2" dia plastic siphon hose jammed down the filler neck. I screwed a long lag bolt down into it and pulled it out (it was stuck pretty good).  thanks for the help anyways guys....

Dude, that plastic hose is supposed to be in there... it vents the tank as you're pumping it so that you don't end up pressurizing the fuel and shooting it back out of the filler neck...

Filler check valve.  I have removed these on other cars when they go bad.  It looks like a "doggy door" and prevents backflow of fuel out of the filler neck.

Unfortunately, you probably have to drop the tank to get to it.  But a stiff length of hose can trip it from the filler neck.

My 2000 Dually had the same problem. It drove me NUTS.

Imagine driving cross-country, towing a racecar trailer and getting 4-6mpg.

I had to stop and fill the tank every few exits. Each gas stop was a good 15-20 minutes... waiting for the gas to trickle into the tank.

When I finally got home from the trip I took care of the problem.

I removed the filler neck to expose the entrance to the gas tank...   I saw a white plastic ball about the size of a ping-pong ball held in place by a few little plastic fingers. It was far enough inside the tank that removing it wasn't an option.

Instead, I took a broomstick handle and jammed it in the opening...  pushing the ball into the tank. I then took the filler neck over to a bench vise and cut out the nozzle restrictor/flapper assy...

I can now fill the tank in record time...
