On my LF38, all three tanks have their own individual vent as they should. The vent line follows the inlet hose and exits the hull just below each fill connection on the deck. The original vent lines are 3/8" gray plastic piping.
A good venting system is necessary to get good flow into and out of the tank as well as insuring that the water pump does not pull a vacuum on the tank and cause it to implode--I have seen this happen on poorly vented holding tanks when emptied.
