Conductive Pipes not working (build craft)

[Ragoras]

Hi guys

i Posted 3 picutres for my problem. I have used 9 redstone engines(currently 8) and 9 wooden conductive pipes, which are connected to the quarry but neither the blue line is visible, nor the quarry is running. I tried it for 30 minutes and google for about 45 minutes with no result. hope you guys can help me.

I don't think redstone engines can connect to pipes.

Oh, they do, but the loss of the conductive pipes is too great for the output of redstone engines.
