So, for a while I've complained about my injectors leaking. I've replaced the return lines several times, and that has not helped. A year ago, I pulled the injectors and put new nozzles and heat shields in. That is when the injectors began to leak. Now, on ********, I see this part...

And I'm wondering what that is (that is, the first two items, not the one pertaining to the IP). I've never heard of this thing, and I surely did not use it on my injector job. Any insight? I'm this close to purchasing six new injectors, I'm sick of not knowing what the problem is. Thanks!
