Since the last update I can not carry liquids (water, lava) with more pumps. There will be no more pumps. I have tested it in the upper world and the Nether. In two dimensions they do not work. Also a newly establish the pump was not successful.

I don't think you can use RedStone engines to power the pump. Try with another engine.

Unfortunately I do not know how much energy does a Engine and how much energy requires a machine for correct functioning. It somehow always missing the necessary information. A pump has no GUI and I do not know how much energy it needs. Conversely, it is so, I can not estimate how much energy a motor correspond produced and whether this is sufficient for a used machine.
Up to version 6.0.18 4 RedStone engines have enough power for a pump supplied. If it be true that they will not be sufficient, so they are slowly but surely but superfluous. In addition to the pump (at least until gates are possible) can then no longer use. This makes the starts but very complicated.

Redstone engines are currently disabled from powering anything but non-power pipes due to the fact that the "free energy" aspect causes gigantic imbalances when combined with other mods. I do not want to make exceptions for other machines.
