ok so i managed to fix the leak on one injector now i have 3. including the same one. no idea whats wrong i hope i dont have to replace anything. the leak isnt nearly as bad with 3 as it was with just 1.

 

Can you blow it off with compressed air or something and see where it's leaking from?

 

its coming from where the line and the injector meet

 

If it were me, I would take the lines off, make sure they're clean, look for nicks on the end of the line or the injector where they seal together, put it back together and tighten down on the nuts. There aren't any seals or anything in there.

 

No nicks or cracks. it was all very dirty i cleaned them up and it works great
