Hmm... are the filters pointed in the right direction? It's hard to see in the picture because of the red alloy wire, but the top and bottom filters point left and the center points right. You can use a screwdriver to re-orient a filter if it's wrong. Make sure you're not clicking the side with the red alloy wire since it will block that whole side -- you can remove the wire temporarily if that makes it easier.

The direction a filter pumps is determined by its red bar. The red bar is the output side, and the yellow&black bar is the input side.

Blacktoothx: It's true that filters are pretty dumb machines, in the sense that they have very limited logic to what they do. However, they're relatively easy to produce and I have a lot of experience with them, so that's what I've been using. I have a friend who uses the red power blocks and likes them -- I need to make the jump at some point.
