Thank you for the SCV explanation.
So today I finally hooked up the pressure gauge directly to the main pump. The pressure was zero (see vid below).

Then, I disconnected the drive shaft to the pump, on the back side of the shaft (not where it couples to the pump). I get a clicking noise inside the pump when I turn it by hand. Sounds to me like a pump issue maybe? Is this noise normal (I doubt it)?
