Other Fuel System Tank Filling/charging problems of the 1999 Jeep Grand Cherokee

I have a leak in my gas tank. I stopped at a gas station to put gas in it and noticed a leak coming from my gas tank before I started filling it. It was dripping off gas tank cover. . . .

After having the gas tank replaced in mid July of 1999, I noticed after driving for over 100 miles, the gas needle on the dash would not move off of full. When I checked the overhead computer to determine how many miles I had until empty, it still showed the maximum. The problem was reported to the dealership in jacksonville and was supposedly taken care of. Last night, my wife and 14 month old child were driving down I-10 and with a 1/4 tank still showing, the car just quit. It had apparently ran out of gas. My wife had to get someone to take her to a gas station and get some gas. After filling up, the same problem appeared as before. My wife was able to drive over 100 miles again without the gas needle moving off of the full position. The day before, my wife had only driven about 150 miles before the car needed to be filled up again. I believe the problem is directly related to the "check engine" light that is being serviced for the 3rd time now.
