I was replacing a burnt out brake light and I noticed this black box down inside the rear fender. There is an identical one on the other side. They have clear plastic tubes that come out of them, but I don't know where they go. I was poking around thinking that there might be a good space down there for a small bottle of NOS, but the space is obviously occupied, just don't know by what. What is it?

Here is where it is located:

Here it is, notice the tube:

the black box acts like a gutter. and that tube runs one from your sunroof and the side that your gas tank is on will have 2 tubes. one for sunroof and other for overfill gas drain

the tube is the drain for the sunroof - there is one on each side

the black box is a vent - it allows air to escape from the car when you slam a door

what do you mean by "frain for the sunroof?" Can you explain? Thanks

Jmai22

when it rains your sunroof might not be totally be sealed and a little water might get down there where the sunroof slides back. so the water runs down those tubes to the bottom of the car.

was going to say the same thing

Thanks everyone - now I know what it does. I just did not expect to see something there.

Those boxes make your trunk sound like crap when you're slumpin'. I filled them up with polyfill material so that the rubber flaps don't rattle like crazy. They still work well, just no more rattle .
