First call the power unit under the hood by its correct name: Diesel ENGINE. The device that cranks it to start is a motor.
There are 2 fuel filters under the hood and a strainer in the fuel tank. One under the hood is an inline filter and is before the fuel pump. The other, a can type filter, is between the fuel pump and the injection pump (IP).
If you don't get dirty fuel or have algae in your tank, the filters rarely have to be changed. If the engine doesn't loose power on long hills, the filters are OK. The strainer in the tank usually only plugs from algae in the fuel.
There is no ignition shut off as Diesels don't have an ignition system. The Vacuum shut off you mention, shuts off the fuel in the IP. With out fuel being injected the engine stops. If the vacuum system does not shut off the fuel, there is a manual rod under the hood that will stop the engine. Look for a rod with stop printed on it.
Pre 1986 MB had manual fuel pumps which are located on the side of the IP. These are used after replacing the fuel filters to prime the system. Often the older pumps leak and air gets into the system thru them, so leaky ones should be replaced.
Maintenance: Oil change and filter 5000 miles for Diesel dino engine oil, 10,000 miles for synthetic Diesel engine oil. Valves should be adjusted every 25,000 miles and timing chain should be checked for elongation and tighteness at same time.
Other maintenence on the car about same as any other car.
Characresistic of MB all iron Diesel engines is extremely long life and good fuel economy.
Eventually you will have to learn how to replace a glow plug (GP)or diagnose the GP system.
