Vacuum gauge inop

While doing a run up, I noticed the Vacuum gauge was not working it was CAVU, and I wanted to make sure the giros where ok - they are. So what can cause the gauge to stop working?

Also the Rear engine Fuel Pressure ( Fuel Flow) middle in the dual gauge is not working. We replaced the Mechanical fuel pump during the annual and the pump works find any suggestions?

Any help is appreciated
