fuel filler problems

Got this yesterday. Very difficult to get in…
Any ideas
Bend the points a bit and use something beveled to try to set it.

I did it years ago and had to adjust it a bunch, without loosing it down too far. It was not much fun. I had wished I could tack it with a welder, but I didn't want to explode or drain and disconnect the tank so I fought through. Good luck.
