Fuel injector adapter cup installation issue

Installed new injector adapter cups as I am installing the fuel injectors, I am having trouble getting two of the injectors back in, so I started inspecting the adapter cups and just as I thought two of them are sitting at an angle. I am not sure how to get them out and try again without damaging them. I do not have a special tool to use, so how can I fix this problem so my injectors will go in?
