Well, near as I can tell, "should" ain't "is." I can't see any holes
other than the "insert water here" hole in the filler port. There are no
side holes in the blue down-hose that I can see with my flashlight.

Besides, where the vent/breather hose punches through the interior
paneling in the forward top-opening compartment is higher than the top
of the tank, so the tank can be overfilled unless there are different
kinds of gravity working over there.

When the tank is overfilled I find water dripping out on the underside
of the van where the side meets the floor.  I'd rather not overfill the
tank again to determine the exact leak source because, well, rust never
sleeps. My guesses are A. The not very good-fitting threads on the big
cap atop the tank, and B. The hole where the pump wire exits the tank
through that funky old grommet.

Exactly the kind of useful information I don't pay you for!
