2.5tdi diesel fuel leak from injector leak off pipes after being replaced.

[white.akita]

hi, i have the 2.5tdi ake engine and it had a diesel leak around all 3 of the injectors on the right bank, so i changed the leak off pipes but they are soaking again with fuel not oil, what could be the problem ?
the new pipes are of good quality and are a nice tight fit.
if it was the injector seals leaking would it be an oil leak or fuel leak ?
im thinking the leak could be coming from the injector seals.
i will buy more new/different fuel line but i feel it isnt that that is the problem, maybe too much pressure ???

I have the same problem on the right side to. I have replaced the pipes twice. I tightened the small bolts holding on the nipples. I think now it leaks from one. I am going to replace the washers on them. I am guessing they are copper washers. If this doesn't fix the problem how difficult is it to seal the injector properly? Can I just nip it up?

They are renound for leaking here, i changed mine 3 or 4 times before i got it leak free.
