Broken part on my Fuel sending unit

I started to remove the fuel pump and on close inspection of my fuel level sender it was obvious to see this broken part with the "o" ring coming out the side. I am curious if anyone knows exactly what this does in the fuel system? I am going to guess that it is the fuel pressure regulator and if this is the cause of my symptoms that I talked about in a previous post about my possible "bad" gas thread here:


You can see about 1/4 inch of separation and the black "o" ring coming out the side

The broken plastic tabs are loose between the two metal pieces

I'm ready to tear into it for further inspection.

The 3.8 bar (55 PSI) that's written on it tells me it is a pressure regulator.

So I went ahead and ordered the entire fuel level sending unit (thanks for the confirmation Pedro!) and put it back into the tank fairly easy. The car runs so much better than I can remember it ever running. I was probably loosing pressure slowly over time and didn't notice until the the regulator came out as much as it did and almost left me on the side of the road. Thanks again for everyones input on this issue.
