Pump not in gas when it's quite clearly in a pool of carbon dioxide

I can also confirm pump not properly being in gas here:

That complete hallway is surrounded by hydrogen

Same here, I had a TWO pumps in the same room, one down low to grab the O2 and one up high to grab the H, the pump grabbing the hydrogen stopped working even though it was in 400-900g hydrogen.  The O2 pump kept going.

There are only 40g of co2 in here. I think the pump considers itself to be in gas when there is atleast 100+g of gas .

Were there 400-900 in each tile or in total? 

I am also having problems with the Gas Intakes.  I have 2 pumps both literally in the middle of NOTHING but pure hydrogen, yet they are hardly taking any in and saying that Gas is not present?w
