Note - the car has not been driven on less than 1/2 tank of diesel since these issues have been identified.
1. No.

2. Did you replace the big O-ring at the prefilter? For whatever reasons, MB doesn't seem to sell the filter and O-ring together. My MB place has filter, prefilter but no O-ring in stock. Could someone have re-used the O-ring?

3. Why are you looking for a restrictor? What is it supposed to do? Not sure what you are talking about.

Doesn't matter. IIRC, these are gravity fed so you can run it till empty and then it will quit.
