The fear of a leak or a failure to get the lines back on properly can be overcome after one session of R & R.
I agree that the gear wrench makes it much quicker and easier.

I think for some members removing the Glow Plugs is there 1st introduction to working on their Mercedes. And, it seems they are doing so without reading any manual.
So they do not want to remove the Hard Lines simply because they don't want to create another problem themselves.
Also from what I have read some folks do not want to deal with bleeding the air from between the IP and the Injectors.
For myself I have managed to drop 2 and lose one of the 8mm nuts even with the Injector Hard Lines removed. So I never plan to change GPs without removing the Hard Lines.
