Such vacuum switches can be tested. It is in fact a solenoid and if 0.00 ohms, it indicates the switch is shorted internally. Try applying battery voltage to the wire while grounding it. Note if there is a clicking noise and test with a vacuum hose to see if vacuum passes through.

Our database does not show anything about the 2 switches and from what I see, they should be attached to something else with another hose leading out.

Does the rich running condition occurs only during low engine speed or at all ranges?

Yes it is an electric fuel pump. And those switches only have one vacuum port, but they connect to two different electrical connectors. Im not sure where the connectors lead to, I havent dug that deep into it yet.
