Flopper Mod 1.16.5/1.15.2 adds Fluid Hopper to Minecraft.
This can be an early-game cube to move around fluids, exactly enjoy the Hopper does for things. It can take in fluids out of the top (either in the tank( or in the entire world ), and also then push it into the side (either to a tank, or to the entire world ). Tanks will always have a preference over world-interaction. Tanks aren’t contained in this mod, but those are Dark Tanks from EvilCraft mod. Everything ranging from the input rate to the cooldown length for world-interaction could be configured in this mod.
