Help with 1997 F150 gas tank

I am replacing the gas tank on my F-150 Ford truck. I want to remove the 2 vent values and the electronic sensor on the top of the tank. I cannot figure out how to pop these out. Thanks

Get a tank from the boneyard with the vent valves and electronic sensor already installed. You'll save some money and won't have to deal with the problem of changing these components over.
