Gas pumps / filters not working

You appear to have a functional Electrolyzer. Might want to read about it.

As for the pumps, they are faster than gas can flow.
Pump sucks in everything, leaves a vacuum, and now there is no gas to pump.

Not seeing where your filter setup is failing. Perhaps you can explain your issue with them in greater detail?
 

Filters fail to actually filter... anything goes through either output of the filter.

I had a filter to send Hydrogen in my Hydrogen generator (had Hydrogen selected for filtered output), and everything else back in the air. In reality, Hydrogen and Oxygen can both go either way randomly. In other words the filter simply functions as a junction with no filtering whatsoever.

Starting from the lower pump:

-the first gas filter should be fine

-you are not filtering anything on the second gas filter. There is no pipe coming out the purple indicator.

-the gas bridge next to the grave is backward. Green is in, white is out. You are doing it wrong.

 

The upper pump should be fine. If you are planning to remove hydrogen, tho, you should place the pump in a higher place, since hydrogen will naturally flow above other gases due to its weight.
