Hi John.
These photo's below may help with removal of the fuel line/rail without removing injectors etc.
You should be able to prise out the securing clips which hold the rail to the injectors.
Use a this blade screw driver.

remove each clip to the front injectors.

You should then be able to lift the rail enough to remove the metal fuel pipe.
You do need to remove the two nuts also holding the rail, I know these photo's show the rail and pipes already off the car but hopefully it gives you the idea, that may help.

Here you can see a little barbed fitting holding in another metal clip which will help remove the fuel pipe so you can get to the O-ring further down the line.

Push the barb fitting then pry up the metal securing clip.

The fuel pipe is held in by another metal clip which you need to tease open to pull the pipe free.

Prise the clip outwards to release the fuel pipe.

With the pipe removed you will see the seal inside.
