Questions about Fluids, Hopper stacksizes and Custom Gearboxes

First, is there a way to prioritize between two fluid inputs without using Aluminium covers? For example, I’d like my boilers to prioritize using Distilled Water returned from turbines and engines, and only then take it from the external tank. I’ve tried using the setup with two barrels on top of each other, but unfortunately it didn’t work. If possible, I’d like to avoid making a separate pipe from turbines/engines all the way to the main tank.

There was a Setup using Fluid Extenders that did that. Heck Bear found that Setup for some reason somehow. it involved 1 Fluid Extender and one extra Fluid Pipe as far as I remember. Maybe try experimenting that out.

Second, what exactly Fluid-o-Meter shows when the value is too large to fit on its display (when it is connected to a 3x3x3 tank)?

You mean the Bucket-O-Meter?

Third, I’m not sure if this is a bug or not, but Hoppers don’t seem to respect their output stacksize limit when outputting to another hopper - a single pulse of 0 signal will make it output its whole contents. If I’ll make it output to the chest instead, it outputs the correct amount. And yes, the hopper was set to the exact stacksize.

It will emit bundles of that exact stacksize, and it will do it once if you only give it a short Redstone pulse. If the Redstone is too long you will end up with the Hopper dumping itself.

Also if you do Hopper->Hopper do NOT vertically stack the hoppers! Otherwise the lower Hopper will just empty the top hopper instantly.

And my fourth question is about Custom Gearboxes. Are they 100% effficient, or do they have some loss due to friction?
Because I’m trying a simple setup where I’m trying to power two Mixers with one turbine (for the Sulfuric Acid production). From my understanding it should work, but doesn’t.
Here’s my setup:
Invar Dense Burning Box (64 HU/t) + Invar Burning Box (16 HU/t)
Strong Invar Boiler (64 HU/t -> 128 S/t) + Invar Boiler (16 HU/t -> 32 S/t)
​Invar Steam Turbine (160 S/t -> 53 RU/t * 66%eff ~ 35 RU/t) (I’m not even sure I should multiply by efficiency, but still…)

All Gearboxes are Lossless during normal operation. Unsure about your Setup though, are you sure it gets enough Steam?
