WARNING: putting multiple tanks on the same system can crash the game. This is a very expensive 1x1 fluid storage tank that holds up to 183 billion fluid. It used to be infinite, but this is the game limitation in Factorio 2.0.6. It is necessary to put a pump at the output, otherwise only part of the fluids inside the tank will drain out. The tank costs as much as 100 regular fluid storage tanks (2000 iron plates and 500 steel plates) OR you can make it directly using 100 fluid tanks. Either way
Mods introducing new content into the game.
known bugs:
-the infinite buffer fluid tank will drain all fluids towards it
-the tank outputs zero fluid. You need to use a pump for the output
-the red/green wire connections are in a strange spot
-once you pick it up, all the fluid is gone, unless it has a pipe connection where the fluid can go somewhere else. Be VERY careful with construction robots deconstruction planner
