Hey folks, for anyone waiting on a 2.0 update, I made a drop-in replacement for 2.0 / Space Age here: One Million & Large Storage Tanks HD
It keeps the same internal name (large-storage-tank), so you can just disable this mod, enable the new one (big-storage-tank-hd), and load your existing save without losing your placed tanks, fluids, or circuit wires.
I also redid the graphics with an animated pump and fluid level indicator, added Bob's Logistics support, and included an optional 15x15 mega tank (1M capacity).
