do you have to remove the injector lines to move the pump? Or will the IP rotate a bit with them connected?

And if you can rotate with them connected...
do you do it with the engine running?


PS:
Do I absolutely have to have an AB timing light/box to replace the IP?
cause I got an IP that has new seals I would like to use.
