Fuel pump/regulator connector part identification

Hi All,

Happy Xmas to you all.

I'm after some help identifying the part in the picture if possible. I was replacing my fuel pump on my 2b (2l pinto EFI) due to the engine cutting out under acceleration yesterday and while fitting the new one I had the horrible moment where everything goes loose and you know instantly that something has snapped. Anyway, I'm not to sure what this part is called or where to get one from so was hoping someone would be able to give me some advice. It's the connector that screws into the pump (PIERBURG 7.21565.01) and the regulator and feeds the fuel back from the regulator to the outlet tube.

In the pics I've put the assembly together so you can see it as it was before I was cack handed and snapped it.

Any help would be much appreciated.

Thanks

Paul
