      It is a drain o some sort, does your car have a sunroof?

              How will water drain upwards?

              It could be for the positive battery cable leading to the battery in the trunk.

                  It's actually a protective tube for 1 (or more) of the fuel vent lines. Seems like overkill to me but maybe it was needed to pass some crash test.

                      I don't think it's for the positive battery cable, I recently relocated the battery back to the trunk and the cable is actually shown in the picture below the "pipe"

                          Cut it in half with a torch, then you can be sure.

                                          More importantly, it dumps into the rear wheel housing, where it's covered by
                                          a sheetmetal cover that corrodes, and the metal 'Y' pipe under there rusts
                                          out and you get fuel leakage in odd situations. Like turning left with a full tank.
