I'd like to use chemfuel generators in order to power my base, but I also want to create chemfuel to sell. Simple enough, but the problem is that any time I am both running generators and pumping out canned chemfuel, I pump too much chemfuel from my tanks and end up losing power to the generators.

So my question is: does the "Fuel pump limit" (the description reads "pump fuel until this amount is reached") mean that only a certain amount of chemfuel is pumped, leaving the tanks full? This is like my third run with Rimefeller enabled and it still makes no sense.
