1996 Mercedes E300 ifi Electrohydraulic shut-off

[veganxxx]

Ok, so i've looked high and low, i even have a Mercedes Tech friend at a local delership that hasnt been able to help me... The vehicle is a 1996 E300 im looking for fuel flow diagram for the electrohydraulic shut-off valve... there is 4 ports on the unit one to the ip, one from the screen filter, one to the lift pump and one from the diesel filter... But what is actuated when that is energized? What ports are open when the valve is deenergized? Theres also a fuel temp sensor in there... What point is it measuring the temp? Any help is greatly appreciated...
Thanks
