So I'm trying to move stuff between two Buildcraft tanks and I'm pretty sure I've got the pipes configured correctly (they all connect to each other and the tanks) but the fluid isn't moving, what do I need to move the fluids? Do I need a pump or something?

What version of IC2 is this? IC2 Classic or IC2 Experimental? If Classic, I recommend heading over to the discord server using the invite on this page: https://www.curseforge.com/minecraft/mc-mods/ic2-classic
