First off, a little run down: A Transposer is the tool you need. Make sure it is facing the correct direction, the big hole should be facing the SIDE of the machine that you are drawing an item out of, and the small hole should be connected to your tubes. The direction of the transposer can be altered by using a screwdriver or sonic screwdriver and right clicking the transposer. Depending on which part of a machines interface the item will be taken from, it will be neccissary to connect the transposer to either: a side, the bottom, or the top. Most machines output to the sides, though a handful will output to the top or bottom. A redstone pulse is needed from either a button(manual pulling of items out of a machine) or a redstone Timer or Sequencer (Automated pulling of items out of a machine), which can be delivered using either redstone dust next to the transposer or red wire directly attached to the transposer, I would recommend wire because dust has a limit of 15 blocks before needing a repeater and is more difficult to isolate. It 'should' be a pulse, though a constant is fine as long as the redstone current turns on once and then off (Like, for example, a lever.  I often test tranposers and filters by directly attaching a lever and testing by flicking it on and off once), the transposer will pull the item out of the machine and place it in the tube attached to it. A filter may replace a transposer, but you should place the item, or stack of items, you want to pull out of the machine into the Filter Interface. This is useful, as an example, for pulling whole stacks of rubber out of your extractor, to keep it from overflowing. One more note: If you do not have a destination for the item, like a chest, the transposer or filter will not put the item in the tube. There must be an exit for the item  from the tube in order for the whole system to function.

Secondly, make sure the machine you are pulling out of is compatable with the REDpower mod, I am unaware of any machines that are not compatable, but it is always worth a check.

I hope this helps! Happy Tekkit'ing!
