To identify the fuel return line, look for a line that connects to the fuel pressure regulator or is typically smaller in diameter compared to the supply line. It often returns to the fuel tank and, in many cases, is positioned alongside or near the fuel supply line in the engine bay. Always consult your vehicle's service manual for precise identification, as configurations can vary by make and model.
