You have to purge the air.
I'm not sure were it is on your car though. Generally it's near the fuel/water filter.
Also, if you do indeed have leaking injectors, FIX THEM FIRST. I cannot stress this enough. The dangers of leaking fuel in a diesel are great. Do not risk it.
Don't "think outside the box".
There is no box.
Do it correct, or do it twice.
