In the driver's side front wheel well is a bulgy-shaped tank of
translucent white plastic. Looks like something that fell out of a cow's
nose, if the cow was the size of a house.

There is a tube, or stiff hose, that goes to it, or sorta close to it.
My son and I found this loose tube today when we were routing wires for
gauge senders from the engine compartment forward. Can't tell where the
tube went or if it's just supposed to hang there, open like that.

What is that tank and what is that tube/hose?

1984, 1.9L, auto transmission. Shoe size: 10W, favorite color: orange.
