Looking closer you may have the three hoses just not installed correctly. The two hoses with green arrows are the siphon output the other is the pressure relief valve (if that fails the siphon also won't work).

All indications are your pump is crooked or the arm to the float is bent. Try to find a photo of a new pump assembly.

The float arm is not raising high enough so it reads low. Bending such that the float starts lower will fix that. You should get max Ω when you put back in. (Including having the cup fixed. Try that first.
