I am trying to make a pump in FTB Infinity Evolved Complete and when I am trying to make the empty cells for the pump I put in the in the tin ingots in the correct recipe form and it does not work. I tried making the universal fluid cells instead but those do not work for the pump. This is very frustrating because the pump is very important for the project I am working on. Also, I have a side question, can I pump lava from a volcano to a geothermal generator in my town?
