yes it does , ive seen the diagrams on the russian link somewhere. ( I think ) the fuel leaves the commonrail manifold , does some time in the alloy fuel filter ( bolted to LH side of engine ) , then goes back to either the main fuel filter or back to the tank. i'll try and find a diagram which will explain it much better than i can
EDIT - cant link the picture but have a look here , part way down the page -
