Iron Tanks
by Indemnity83
Iron Tanks adds tiered fluid tanks that grow in capacity, stack into one larger tank and can be upgraded in the world without spilling their contents.
What it does
Iron Tanks brings the storage progression of Iron Chests to fluids, following the same pattern of better materials and bigger tanks in one block footprint. Tanks come in several tiers, and some tiers depend on which materials the Minecraft version or the modpack makes available. Obsidian-built tanks withstand blasts, a void tank voids whatever is piped in, and creative tanks hold an unlimited amount for testing.
Modern releases no longer need BuildCraft for their core function and work as a standalone fluid storage mod, though BuildCraft is still listed as a required dependency. Fabric API is required on Fabric. Logistics: Automation is an optional dependency that adds automated movement of fluid into and out of tanks. Iron Tanks is client and server, so the server and every player need it, and it is released under the MIT License as open source.

What the author says
Iron Tanks is the original tiered fluid storage mod for Minecraft: better materials, bigger tanks, and more compact storage in the same one-block footprint. The mod began as a BuildCraft add-on, bringing the same kind of storage progression to tanks that Iron Chests brought to vanilla chests. That legacy version is…
