fuel injector pipe leak

[weirdfish]

I have a leak from 2 of the 3 injector pipes at the top, ( the long nut ), it appears to be running down the nut and not from inside down the pipe.
I've taken the top flat cover off one of the offending cylinders to see if I could work out where it might be from, this is what I'm looking at, how does this come apart, or, where might the leak be coming from.

I’ve taken the return fuel pipe off and it’s still not obvious how the injector comes out, although I did have a quick look at an online manual and it mentions the use of a slide hammer.
Is that the only way to remove them?

If the workshop manuals says that is how to remove them and it is your model then that is the way to go. Do aGoogle search or a YoujTube one on how to remove your model engine injectors.
