And -- use extreme care, because a stuck quick connect is far better than a broken quick connect!

Good luck!
These disconnects have a rubber o-ring which gets stuck. I'd say, use the tool and maybe give the connection a drop of penetrating oil and keep trying. Good luck, and don't spray yourself with fuel when it comes apart.
Best suggestion under the circumstances is to get it to a professional that does these several times a day. It's quick and easy for someone with a lift to get up there and remove it with some experience behind them that will keep the fuel line from getting fractured.

A fractured fuel line is a bad it's best to elect for the safe bet.
