Hi there,
I come to signal a bug when I use a tank an a wooden fluid transport pipe for give lava at one lava generator of other mod. the lava don't go at the machine

BuildCraft version: 7.99.8.1
Forge version: 13.20.1.2588 for 1.11.2
Link to crash report or log:
Singleplayer or multiplayer: Multiplayer
Steps to reproduce: tank of Buildcraft and wooden tfluid transport pipe of bc transport and magmatic generator of extrautilities 2
Additional information:

can you provide pictures of your setup? fluid pipes work fine so most likely something isn't hooked up right

yes, at the begin, When I installed the setup, it worked, but after one moment, he dont
Picture follow message

yeah i see your problem: wooden pipes do not extract on their own. They need to be powered, you can use a redstone engine next to it or put a pipe pulsar on the pipe itself (see guide book for recipe)
