Can I just unbolt the fuel rail from the intake manifold?

Hi people,

I need to replace the rubber fuel lines to and from the fuel rail in my car, but I can't get to one end of the fuel rail as the feed is underneath the intake manifold... (see pic, blue arrow).

Can I just unbolt the whole fuel rail (three red arrows) and then bolt it back up? Is that safe or do I have to replace o-rings etc etc for the injectors? New o-rings were put on when the intake manifold was installed in December 2003.

thanks
