Been searching all over for a photo/diagram of where the glow plugs are located on this engine. Can someone point me to that? Much thanks -Dan

Sorry if this is a repeat...newbie here. Trying to find a pic or diagram of where the glow plugs are located. All shrouding is off and can't tell if on the one side they are to the left or right of the fuel rail. Thanks -Dan
