My quarry setup looks like this, and it's been working pretty well so far.
I could disregard the Buffer and continue on with BC pipes, but I don't want to waste a billion Diamond Pipes as well.
Too lazy to get a system to automatically process and craft everything, so this is kind of enough for now.
[edit] And so I don't get completely off-topic, you could erase items from your RP system (without TubeStuff) by filtering them into the air, where they're caught by a BC Obsidian Pipe and sent to a Void Pipe. It might be a bit laggy, I guess.
Code:
Quarry -> Tesseract
Void Pipe (cobble, dirt, sand and so on)
^
Tess -> Diamond Pipe -> TubeStuff Buffer -> Filter -> RP tubes -> a billion barrels -> overflow chest
v
Apiarist chest or whatever it was called
