Mine does not. I have attached a picture from underneath that shows my setup. The engine supply and return lines come off the side of the two tanks and curve up and over the transmission where they connect to the equalization system components. Nothing connecting the bottom of the two tanks directly. My chassis was manufactured in late-2013, I wonder if Jayco or Freightliner changed something?
The crossover lines I saw on semis were a hose of at least 1" diameter, sometimes bigger. Does yours have something like that?
