You can't service the injectors, they are a sealed non servicable part. You can remove and refit by yourself. Replace the seals while your at it. You should replace the injector pipes as the manual says because you will have around 30,000psi of fuel pressure through them and if you could damage a pipe or connection without knowing. There's no oring in them too.
