Service went wrong- fuel filter

[Lalbxxdh]

Hello guys!

I did my first ever service for my Insignia eco flex 2014. Everything went well, changed my oil, oil filter, air intake and cabin filter. I was going to leave the fuel filter for another time but decided since it all went well this far, I might as well change it.

As I tried to open it, I ended up pulling the fuel housing off its mount and heard a snap. I carried on as normal thinking that it might have just came from the movement of the mount.

Turns out after switching the electrical systems on once closing everything up, there was a huge leak coming from the filter and tank area.

I saw this part snapped:

Does anyone know what is wrong, how much this will likely cost me and how easy it is to obtain the parts?

Thank you!
