Okay. Your Wooden Transport Pipe is facing the wrong way. See the little Wooden rectangle? It should be on the Chest's side, not the Generator's bottom. Use a Buildcraft Wrench for that.

If this is a recurring problem, I recommend switching to RedPower2's Pneumatic Tubes. There are no orientation problems with those.
