new injector day

Hello, some photos of changing my injectors and corresponding vacuum lines. It has been fairly easy so far. These injectors are original (149,000K). I have been purchasing parts all winter leading up to today so it feels like Christmas. I have never attempted anything like this before so I'm feeling a little freaked out but so far so good. Do the green seals in the injector holders that go in the engine fit in the engine as shown in the picture or do they fit underneath? If that makes sense? They do not seem to fit they way shown, too big? Has anyone ever done this before?
