help identify a clear hose on the driver side

Can someone tell me what is that clear hose on the left side of the car. Its where the gas lines is at.

near the filler neck, behind and underneath it? the one connected to that lil drip hole?

Sunroof, drain line. there are four of them that run down both sides of the car, front and back (A & C)pillars.

not all da’s/db’s have sunroof’s. but if its in the interior its possible. the clear lines are always drain lines for water or whatever. OP has an LS (may have a sunroof but i dunno).

The blue is where it is, I couldnt follow it after the seat.

rear windshield sprinkler?

^^^ rear windsheild spray.
