 FUEL SUMP DRAINING
__________________
General
_______
 A.  This procedure contains two tasks. the first task gives instructions to drain the fuel tank sumps in the main, surge and center fuel tanks. The second task gives instructions to remove the poppet valves for the sump drain valves to let the fuel drain faster from the main, surge and center tanks.
 B.  The fuel tank sumps must be drained regularly for the removal of the water from the fuel tanks. Each fuel tank sump has a drain valve that that drains the water from the fuel tank. Before you sump the tank a quantity of time is necessary for the separation of water from fuel. The time rate to isolate the fuel from the water is 1 hour for each foot of fuel depth.
