I'm trying to find the secondary fuel filter (clear plastic one). I've taken off the both parts of the air filter and have a clear view of the injection pump. I can't seem to find this filter though. Everything I've read indicates it should be right behind the box. Any thoughts?

 

In reference to the 190D. Here's a pic

It should be down somewhat near the engine mount and it could be like a darker color from particles being inside

 

Nice display with the pic

 

Awesome man thanks. I just looked. Mine is a little different. It looks like it might be aluminum, but its definitely the one. Can't wait to take it off. If its as bad as the big filter, car should totally run better. Thanks again.
