That picture is for the 124 implementation of the OM 606 (in the U.S. It was the 1995 E300D), that still used vacuum shutoff that acts on the rack, so is not shown in this picture.

The 210 (starting with 1996 in the U.S.) uses electrical shutoff, and has an additional electrical shutoff valve on the IP that directly interrupts the fuel flow.

I will try to look later for a picture of the 96 system and post it.
