The electric pump is not pumping liquids and is not saving the upgrades each time i goes to menu and load the save again, i tested with only the four Mekanism mods installed.

Minecraft 1.19.2
Forge 43.2.3
Mekanism 10.3.5.473

For some reason i don't know it is working now. When i removed all my mods and loaded my save with the already placed pump after some minutes the pump started working, then i added my mods again and it is working now. It is even saving the upgrades. Sorry for the issue ticket, it wasn't working no matter what i did so i thought it was a bug.
