What is this?

I just noticed this thing today hangs downwards next to "Back right side tier" And was wondering what is it?

I think it’s the drain tube for the drain near the fuel flap.

that is correct. it is a drain for the fuel filler flap.

p.s. the fuel filler compartment has a very small whole that tends to clog up rather quickly.
you can use some compressed air with a straw nostril to blow out the clogs and watch them shoot out that small pipe
