[1.12.2] Fluid tank slot and buckets

[Terrails]

Here's the issue, I wanted to add a slot with which I fill my tank. When it comes to buckets it works when there's at least 1000 mB empty space left in the tank (then it empties the bucket and puts it in the slot which has empty fluid handlers), but when there is less then 1000 mB it fills the tank infinitely and doesn't drain the bucket (it doesn't do this with tanks from mekanism, thermal expansion etc...), what would be the best way to make sure it doesn't do this?

Never mind, looks like I made it work!
