Issue Detail

In the pack I have made, the interaction with a Supplementaries Faucet, and Pneumatic Craft Thermopneumatic Processing Plant allows for duplication of any fluid inside the Processing Plant, if a Faucet is attached to it.

More details can be seen here from my original report:
TeamPneumatic/pnc-repressurized#1290

The dev of PNC suggests:

"This is absolutely a problem with the Faucet, which is misusing the forge IFluidHandler API. The faucet is extracting an arbitrary tank from the fluid handler it gets and extracting from that. The arbitrary tank is picks is tank 0, the input tank.

The correct way to do this is to call drain() directly on the fluid handler itself, not mess about with the tank internals."

Thanks seems to be working as well!
