Basic Pressurized tube wont connect to purification chamber in survival, when I tried in creative mode it connect, sometimes it won’t connect electrolytic separator , I think Basic Pressurized tube randomly wont connect..

Mechanism Mod I used:
Mekanism-1.16.4-10.0.19.446
MekanismGenerators-1.16.4-10.0.19.446

How is the side config of the machine setup?
