2008 C4S. Need a part number that I cannot find in my current exploded parts diagram.
On the fuel collection pipe, there are two 10mm torx machine screws (part 90038504109). They hold the pipe down. There is a nut that is like a bushing that it connects to. I need the part for that nut. thx

 

I'm only seeing 900 385 041 09 Torx Screw M6x12 referenced in two places in the PET diagram for that year/model. Does it screw into the intake manifold?


Here's the links:

yeah, those are the same diagrams I have, and I dont see it on there.
I looked through and the only thing I see that looks like the part that the mentioned screw fits into is called a screw stop. But that's in another place on the car. This "nut" actually sits under whatever the fuel pipe is attached to, and when the screw is removed, it falls out easily. Well, while I was changing my injectors, this one fell into never land. Magnetic retrieval couldnt find it. I ended up just using a 1/4" SS bolt with nut til I get the correct part.
If I had to describe the part, it's a threaded cylinder, with a small washer on the underside that is larger than the diameter of the cylinder.

 

Here's the workshop manual instructions for removing and installing injectors: https://drive.google.com/file/d/0Bx1...it?usp=sharing


On page 8 the fuel distributor pipe connects to the intake manifold with the screws #1 in the diagram. The torque is 7.5 ft-lb. It doesn't show any nut on the other side. Are you sure all four screws have this sleeve/nut as you describe? Perhaps it is supposed to be press-fit into the intake manifold and for whatever reason yours popped out?

 

Maybe this is naive, but: If there is another one elsewhere on that assembly, maybe you could take one of the other ones out to see exactly what it looks like and find another one that way?

 

yes, there are 4. One on the driver side popped out as well and I was lucky to find it and reuse it (they do not seem to be pressed in, come out easily). So I know what it looks like. Just puzzles me that it's not on the part diagram.

 

Went to Harbor Freight and got one of those cameras ........damn this thing is handy. I found the part in question in a crevice beside the injector.
Here she is:

 

Awesome. Any chance you can get a picture with the camera of the part installed? I'm curious to see how the fuel connection pipe attaches to the engine vs. the PET diagrams.

 

Sure. Green arrows are the torx screw, and they screw into the part I asked about. There are some little tabs coming off the valve covers that the pipe is affixed to.
