Sorry guys, but for me the GSX fuel truck will be stuck in initial position after the refuel is completed...I use FSLab refuel panel but GSX don't recognize it and give the possibility to choose a percentage of fuel or use P3D Fuel Loader. I ignore this message and start refuel via FSLAB panel; then Fuel truck start to do is job but when reach the target remain stuck in refuel position and does not go away even I put OFF on Fuel Panel of A320.
