Fuel Injector Question

Has anyone worked their way down to their injectors and know what the little PCV Valve looking piece is? (has a vacuum line running towards the battery on front and back) It sits through the fuel injector wiring harness into the intake runner?

If anyone has diagram of that area I can point out where it sits.



Thanks in advance!

Right above number 11 in the bottom left of the picture. There is a tiny hole next to the middle injector hole. what hooks up there with the vacuum line?

That pain in the ass left me with a vacuum leak for two weeks until I could source the part. If you've never touched the injectors or runners before, no matter how clean that engine is, it might just break off. It's annoying as heck. It's #5 2001 Acura CL TYPS 5AT TUBING

That is air assist to the runners.

On my car those holes are welded closed and other parts removed. It is not needed.

Ahh thank you!! I looked everywhere for it .. but it was under tubing! To re install did you have to remove the runner? Or did you just push them through the bracket? It seems like they twist into place and there is not alot of side clearance (Valve covers in the way)
