My 120 diesel has 2 x 90 litre tanks. Can someone explain how the filling system works?! It seems to have a simple Y piece linking both tanks to the filler. Does it somehow prioritize the front tank when filling? Is it a simple gravity system so the rear tank only gets fuel when the fill line backs up to the Y piece? Or is there some kind of valve in there? I can’t understand why I don’t end up with both tanks part full which would mess up the automatic switch over system. And how does that work?!
