Part 2/5:
The current pump he is using can typically achieve pressures of around one to two millibars. Although the pump’s label claims it should reach pressures as low as 0.1 millibar, Hank mentions that it does not achieve this target, highlighting a performance limitation that often comes with using older equipment.
Chemical Reactions and Their Effects
One intriguing aspect Hank discusses is the transparent plastic indicator on the pump that shows the oil level. This indicator has become cloudy and opaque over time, suggesting a chemical reaction has taken place. Hank speculates that he has drawn chemicals from the tanks into the oil, which is a point of concern for the integrity of the pump's functionality.
