I found these two:
Attachment 65901
Attachment 65902
The white/yellow plastic thing is bolted into the tank. I'm planning on installing the deloreango.com fuel pump replacement, that I got for my birthsday, but I can't figure out wether I need to remove or keep the plastic widget in the tank.
The brown disc-shaped thing was just laying loose inside the tank. I don't suppose that is worth keeping?
