I will be upgrading my fuel rail (for the first time) and was wondering if you just "push in" the injectors into the fuel rail and bolt it back onto the IM? (I already read one on-line "how to" on it, but it did not go into detail with the injectors.

I believe that the Honda OEM injectors have alignment marks on them? (Align install into the fuel rail?) Thanks in advance for the help/advice.

 

The injectors just push in. Use a little oil on the O-rings and try to push the injector in straight. Less chance of damaging the O-ring this way. The alignment doesn't seem critical for anything other than the injector connectors.
