Filler flap restricting fuel

I have a Buick Lucerne. The little flap door at the filler nozzle has come off. Now I have to fill my tank a pint at a time. It takes me 15 minutes to put 5 gallons of gas in. Any suggestions of how to get it out?

Remove the fuel filler neck. Either it will be in reach or it will fall into the gas tank.

Not sure how to do that on my car

Then maybe you should take it to a good independent repair shop and let them do it for you.

G nah, I’m too cheap for that I’ll just find a manual or something to figure it out dot-dot. Thanks
