735i - Getting the fuel injectors out

I saw that someone had posted this question before but no answer was
posted (back in 2002). I want to re-address this question.

The Bentley manual says to remove the fuel injectors by "prying" up the
fuel rail. It says you should do this until both the fuel injectors and
the railing comes off as one unit. I've tried doing this and all I get
is the sound of plastic cracking. It seems like I am damaging the wire
harness casing that runs alongside the fuel rail. I'm probably also
damaging the part of the engine that I'm using in order to get leverage
to pull the injectors up. I read on another site that you shouldn't use
pliers or screwdrivers to get the injectors out because you will damage
them. My neighbor says that my injectors are probably rusted, but I see
no signs of that. How can you "safely" get these injectors out without
causing more damage to your engine?
