Those blue "check valves" are not needed if your air pump sits higher than the water level in your res or DWC system.
Never had mine interfer with air flow before, although I no longer use them.
My air pump sits on my hood so the light doesn't heat it and my air up.
The rubber feet keeps them from getting hot while on my hood.
