The connection is a quick dissconnect, I unpluged the line by pushing up on the bottom of the fitting and pulling down on the retainer . This allowed me to unplug the line. I then removed the fitting that was threaded into the tank and found the rubber "O" ring was bad, I replaced the "O" ring and put the parts back together. ( i sprayed a little WD 40 on the Quick dissconnect and applied a small amount of "O" ring lube to the ring prior to putting everything back together )

Replace the petcock. The rubber diaphragm is ruptured. I'd also bet your fuel mileage dropped cause the ruptured diaphragm is allowing raw fuel to be sucked into the intake manifold.
