Tanks & Barrels
Tanks and barrels are useful storage devices that can hold various fluids in various amounts. Each tank and barrel supports holding different types of corrosive, hot, or exotic fluids, and knowing which ones can hold your desired fluids can be vital to your fluid processing and storage facilities.
Usage

Set the fluid by putting a fluid ID in the top slot of the GUI, or crouch right-click the container while holding a fluid ID, then fill it up with slippery goodness.
Fluid containers are set to input mode by default, clicking through the button will switch between input, buffer (input and output), output, and no access modes.
Barrels
These single block barrels can store reasonable amounts of fluids, with varying capacities and capabilities. Note that the item fluid barrel containers hold 16,000mB and cannot be partially filled, and therefore need to be placed in a barrel at least as large as a steel barrel to extract their fluid.

Safe Barrel
This barrel can only store regular fluids, and has a capacity of 12,000 mB

Iron Barrel
This barrel can store regular and hot fluids, and has a capacity of 8,000 mB

Corroded Barrel
This is what iron barrels turn into when corrosive fluids are placed into them, it has a capacity of only 6,000mB it will constantly leak fluids until it is repaired or replaced. They can be repaired by combining one with tar in the crafting table.

Steel Barrel
This barrel can store regular, hot, and corrosive fluids (but not highly corrosive fluids), and has a capacity of 16,000 mB

Technetium Steel Barrel
This barrel can store regular, hot, and both corrosive and highly corrosive fluids, and has a capacity of 24,000 mB

Magnetic Antimatter Container
This container can store any fluid, with the downside of being very expensive to craft, with a capacity of 16,000 mB
Steel Tank - Fluid Barrels
Steel tanks are used in many crafting recipes, and can also be used to place tanks of diesel, kerosene and liquid oxygen into the world that can be shot at, causing them to explode. The tanks can be filled with 10,000 mB of the chosen fluid, and they can also be emptied to retrieve that fuel by placing them in a barrel with a capacity higher than 10,000 mB.
Steel tanks can also be crafted into radioactive barrels at an anvil, with lead plates and nuclear waste.

Tank

The tank is likely the first multiblock fluid storage device a player will make in their survival playthrough, and requires basic oil processing in order to produce the required oil tar, though a combination furnace and an industrial solidification machine can be used to produce wood or coal tar as an alternative. It can store 256,000 mB (or 256 buckets) of most fluids except for:
The tank has two access ports available on both sides of the tank near the bottom. Crafting the tank requires an assembly machine and the following materials:
Big-Ass Tank 9000

The Big-Ass Tank 9000 (patent pending) is the largest fluid storage container in the mod, capable of storing a whopping 2,048,000 mB of fluid. Due to the technetium/cadmium steel present in its construction, it is also capable of holding strongly corrosive fluids, but antimatter will still cause the destruction of the tank.
This tank has two access ports available on each side, for a total of 8 ports. Crafting the tank can be done in an assembly machine with the following recipe:
Heavy Magnetic Storage Tank

The heavy magnetic storage tank is the only multiblock tank capable of holding any fluid. However, it is, again, very expensive to manufacture.
This tank has four ports on both the top and bottom for inserting and extracting fluids, and can be crafted in an assembly machine with the following recipe:
Notes
- The ladder is usable on tanks that have them, even though it was thought to not be possible to implement.
- Stopping midway is somewhat broken, but is a minor problem.
- A tank may also be a massive, muscular zombie that threatens to kill your three teammates in a single blow.
- May also be an armored fighting vehicle intended as a primary offense weapon in the frontlines.
- Used to use a slot for a fuse, it no longer uses a fuse so it won't do anything, but fuses from previous versions from the tank can be recovered.
- Can fill/empty all of its contents at once.
- When shot with an explosive or filled with strongly corrosive fluid, tanks will get damaged and can be repaired with a blowtorch and steel plates.
