On my Haulmark ( Freightliner) if I fill one side right full by the time I slide the hose underneath to fill the other side (my favorite station is only single side) the first tank will have dropped a couple of inches, even with the engine off. All of the big trucks (Peterbilt, Kenworth, Western Star, IH) I have driven were the same.

There are no pumps just a Tee fitting with equal length hoses (very important) and it works on the siphon principle.
