What happened wrong?

Furnaces, after updating the config, are not exporting XP to the Kibe tanks attached to them.

I don't understand what you mean by "updating the config". Has it ever worked for you before? Or after setting to the correct fluid?
Anyway, Liquid XP can only be extracted from the horizontal sides (or any sides in newer versions and without the Liquid Fuel Upgrade installed)
