simpler to have the vent hole above the top of the tank. Add a sleeve
to prevent splash possibility.

It has to be "in" the tank. The pump will squirt water everywhere.

What I'm suggesting is a 1/4" hole in the panel output pipe just above
the top of tank, say 1/2" above. There will be close to no pressure
there, and no possibility of any squirting.
