What is this on the fuel rail and how do I fix it?

I can't figure out what this is, but it leaks... With my 14 month old daughter with me every day, i can't risk a fire since this is just over the exhaust manifold as well. I know it is not the fuel pressure regulator, as it can be seen in the bigger pic to the far left with the red vac hose and electrical plug. I think this may be the fuel pulse dampner, but can't find anything for sure or how to fix it.

My ink pen is pointing at the problem in the pics.

If you know for sure what this is, or how to fix it, please let me know!!

Yes, that is the fuel injection pulse damper. I'm not sure if you can remove it from the fuel rail or not. You might have to replace the whole fuel rail. Can you take a picture underneath it to see if it has a hex head or threads showing?

Is your car flex-fuel?

it may have a snapring holding it down, clean it up a bit and see if you can see the ring in there.

Yes, there is a snap ring on top. But I don't really want to open it up until I know that parts are available for it, for fear of making it a major leak where the car won't run. The base portion is part of the fuel rail, it isn't threaded in, it's molded in then the snap ring I assume, lets the top half come off

And no, not flex-fuel. Just the standard 3.0L.

Well, I found the part but it's going to be dealer-only (**8Z-9F775-AA). And it's probably going to run about $70-100. Otherwise you can probably find one at a junkyard (looks like they used these on 2002-2003 only).

Where is it leaking? If you're luck you might be able to take the old one out and just replace the O-ring.

For those trying to fix the leak, here are a few pictures of my old damper. I'm not going to replace it, new part is about $90. I just cleaned inside, hoping the leak will stop. Might look for a replacement o-ring, any idea who might have it? It has to be gasoline resistant (fluorosilicone?).
