Afacilitate water removal
Bprevent loss of suction during rough weather
Cdecrease suction head on the pump
Dincrease the amount of fuel available for use
AI Explanation
The correct answer is A) facilitate water removal. The main reason for having a low suction line on the fuel oil service or settling tanks is to allow the water and other contaminants that settle to the bottom of the tank to be easily removed. This helps maintain the quality of the fuel by separating out any water or sediment before it is drawn into the fuel system. The low suction position ensures that the pump can access the water and contaminants at the bottom of the tank, rather than just drawing from the cleaner fuel at the top. The other options are incorrect as they do not address the primary purpose of the low suction line, which is to facilitate water and contaminant removal from the fuel tanks.
