Question

Quizplus · Accepted Answer

Fuel filters are generally located in the fuel supply line and not in the fuel return line. As fuel flows from the fuel tank to the engine, it passes through the fuel filter which removes impurities and contaminants that may clog fuel injectors or damage other engine components. The fuel then reaches the engine where combustion takes place, and the unused fuel is returned back to the fuel tank through the fuel return line. Therefore, technician A is correct in this case.
