More Perentie questions

[Bolton]

Hi All. Still exploring my recently acquired Perentie. What is the U shaped device mounted on the bulkhead at the front of the tray that you can move up and down?

Cheers

It is the breather for the diesel tank
It can be moved to a different location but try and keep the height the same
One end goes to the tank the other vents behind the cill rail.
Fuel overflows from it when you overfill the tank
