1- you have the windshield washer pump

2- the washer pump grommet goes bad also that could leak

3- the fluid level sensor : will have a electric connector on it not a hose.

4- the bottle itself might have a tiny crack in it

as far as the that nibble that looks a cover or a hose gets attached to it , if it is what u see in the diagram i sent you , then that should be the water feed line that should be connected to the washer pump and from there it goes the washer system.

you can send me a picture if you like of what you seeing so i can confirm for you .
