These loaders function similarly to your basic Loaders, however they are designed to work with Tank Carts.

Liquid can be piped out of the Liquid Unloader with BuildCraft Pipes. It also has an internal capacity equivalent to eight buckets. Additionally, if you put a bucket in the Filter slot of the GUI, they will only fill/empty carts carrying the same liquid as the bucket. If you put a minecart in the cart slot it will fill/empty only carts of that type.
