Question 1981 240D Racor Fuel/water filter?

Hi, I just bought a 1981 Mercedes-Benz 240D and I am going to change all the fuel filters on it. After ordering the pre and main filters I recently descovered it has a third filter on it, a racor 200FG fuel/water filter. These filters come in three micron sizes 30,10,2, which one should I use?

I don't think you need it at all. I believe all US gas stations have double-wall tanks, so water condensation is non existent. I never have seen water in diesel for last 20 years.
I had Racor filter installed by PO on older VW,. While I never have seen water or dirt in it, it become a headache with leaky orings in hard to find sizes. I got rid of it

thanks for the quick reply

thanks for the quick reply, The trouble is here that I live next to a truck stop and almost all the time I fill up my 5 gal Diesel can it usually has 1 to 4 ounces of water on the bottom, I have tried all the stations here (BP,shell,pilot) that sell diesel fuel, I have even had semi truckers tell me that a little bit of water in the fuel is not harmful to a diesel engine.

There's an awful lot of trashy, contaminated fuel on the open market. I've used Racor fuel/water separators for over 30 years on big rigs and its surprising the amount of trash and water they can collect. If you keep it drained of water and change the filter element regularly, it likely wouldn't make much difference as which micron size element you use. I'd go with whatever element is most readily available, and if they're all available and the same price, I'd probably pick the 10 micron size.
