Take the air tram to the car rental center. Take the elevator to level one. Go outside to your left and cross the street partially to get to the island (labeled Island 2 even though it's the only actual island). There are two benches with a phone between them. If a Fox shuttle isn't already there, use the phone to dial a single digit corresponding to the Fox Rental logo. It will connect you directly to them and they will send a shuttle.
You have to take the AirTran to the car rental stop
