Does anyone know where the suction pump is located on a 98 V6 Quattro 2.8L AHA????
I've been looking for it and I can't find. I found the breather hose but no suction pump.

Thanks.

 

Never mind. I found it here for those of you who are thinking of replacing it.

I replace my suction pump today. However I am wondering how do I tell it is plugged or need to be changed? By looking into the holes, I didn't see a difference between the old and new one.

The other question is that how do I clean the old one?
