open atmosphere fluid tanks?

The reservoir has no pressure inside of it. The “overfill line” in reality is a vent/breather for the reservoir. Check out this link for more info on the differences of vented and non pressurized reservoirs.

I built the super dumpers hydraulic tanks just like my 1:1 kw's tanks with vents. It's gotta be vented or you get hydro block and fluid don't flow
