Thanks guys.
Although I have net figured it out yet.
My car has a intake just like a gas-car, this is where trouble comes in.
The "mixture" between air and diesel, unknown.
I need to know the approx. settings on this diesel with air-restricted intake.

I know on the 240D the linkage goes past the "throttle" which I dont think exist on that car, it is just the easiest way to link it together.

Drilling a new hole seems like a good idea, were thinking about that before.
The first part of the linkage is ok, it is after the throttle that travel is too short.
The hole will be drilled in the plate near the pump.
