The fuel pressure gauge will not tell him about a plugging fuel filter if the filter is in the carb fuel-inlet fitting. The restriction would happen downstream from the pressure-tap for the gauge.
If the pressure reading is taken downstream from the filter, it should be a reliable indicator assuming the carb has appropriate float-drop.
