Unless I'm just having a lot of trouble getting the filter to work, I can't seem to get it to pump CO2. It will pump hydrogen, oxygen and chlorine, but when I select CO2 it does nothing.
Steps to Reproduce
create a lot of CO2 and set a gas pump in it, wire a filter to the pump and power to the filter. Then select in the filter to filter out CO2. After that run the filter slot pipe to a air vent. Pump will then not pump out co2,
