Renault 2.2 dci fuel loss

Hello friends, here I write to another problem again, it turns out that four days ago fuel began by some small "plastic distributors located on the injectors, these devices are fixed with a clip to the rest of the injector, I attach a photo to clarify.
They would greatly add their comments or if anyone had a similar problem.
Thank you

Change injectors

Hi Alfredoe2264, I have not seen the photo you say but in images of that engine on the Internet is direct injection and Common Rail system. Those tubes you say is a high pressure injection system. It should not be expensive but better that you go to a professional if you do something wrong does not work and if when you release or mount dirt and load an injector that is going to be expensive.
Luck.
