Which component indicates an obstruction in the suction line?

Oil strainer
Main burner
Vacuum gauge
Flow meter

The correct answer is: Vacuum gauge

The vacuum gauge is the component that indicates an obstruction in the suction line because it measures the pressure difference in the suction side of the system. When there is an obstruction, the flow of the fluid is restricted, resulting in a lower pressure or more significant vacuum reading on the gauge. This reading helps operators identify issues in the suction line that may hinder proper operation, making it an essential tool for ensuring the system is functioning effectively. Other components, like the oil strainer, serve different purposes such as filtering out debris from the system; they may indicate problems like clogging but not specifically measure suction line obstructions. The main burner and flow meter also do not measure pressure directly related to the suction line, focusing more on combustion and flow rates, respectively.
