Fuel Tank problem

[devinlamothe]

Hi everyone,

Here's my issue. We have a ton of pot holes here so this doesn't surprise me but - the other day I started to hear this knocking sound coming from the rear passenger side. I didn't think anything of it, as when it gets cold, I tend to hear a lot of creeks and such. But this kept on going and this morning I had a peek under the car, and I saw something bad.

There's a piece of metal that is covering the bottom of the fuel tank, and its coming off. I don't know if this is a critical piece but I would like to fix this ASAP. Anyone know what this piece is for? Should I be extra worried? I have a road trip planned for next weekend so any help is appreciated!

Note: I am brining to my dealer but they are booked until next week.
