Q

MASTER WARNING

FEED TANK 1 or 2

A

Case 1: if one fuel system gauge reading is zero, then the fuel quantity in the corresponding feed tank is below 37 lbs of JP5
Case 2: if the fuel in the corresponding tank system is greater than zero and fuel pressure is normal, the fuel ejector system has failed
Case 3: if the fuel in the corresponding tank system is greater than zero and fuel boost pump pressure is zero with BOTH boost pumps on, a dual boost pump failure has occurred.
