ABooster pump suction.
BPurge valve discharge.
CFuel oil day tank.
DBooster pump discharge.
AI Explanation
The correct answer is D) Booster pump discharge. The fuel oil back pressure regulator is designed to maintain a constant pressure in the fuel supply line by returning excess fuel back to the booster pump discharge. This ensures a consistent fuel flow to the engine, which is crucial for proper engine operation. The other answer choices are incorrect because: A) the booster pump suction would not be the correct return point, as that would disrupt the pump's operation; B) the purge valve discharge is not the intended return path for the back pressure regulator; and C) the fuel oil day tank is not the appropriate destination for the excess fuel.
