I've been using Mann filters for oil and air. And I have a supply of Mann fuel filters for the W123. Just put a Bosch fuel filter on the W124 because I needed it quickly and FastLane had those.

I'd like to relate what I found on changing the W124 air filter. It looked fairly clean on initial inspection, but on the diesels of that series its a big square thing - very deep channels. So when I pried apart a few of the folds in the filter all kinds of stuff started falling out.

Anyway, I got the new Mann filter and had the old Hengst by it. I noticed the Mann said "Made in Germany" and the old Hengst said "Made in WEST Germany" (my emphasis). So I started laughing and thinking about just how old that filter must have been!

Let's see, the Berlin Wall fell in 1989. I forget how long after that the sides merged, maybe five years?
