DRAINAGE PROVISIONS. - Fuel system components having shaft
seal compartments such as in pumps, and strainers} and any
other fuel system component requiring cleaning, shall include adequate drainage
provisions. Drain valves, in other than a vertical configuration of the lowest
point, shall be installed in such a manner that the valve will be at the lowest
practicable point and tilted efficiently to permit adequate draining when the
target is in its maximum nose-up and nose-down attitudes on handling truck or
launching device. Drain valves shall be designed to permit removal and replace-
ment of the rubber goods without draining the fuel tank.

collecting fuel drainage from the fuel manifold dump valves
and drains from pertinent accessories such as flow dividers, pumps, etc., when
the target is at rest in the normal attitude on the handling truck or launching
device, leaving no raw fuel in the fuel-manifold. The container shall be of
sufficient capacity to provide one normal shutdown and two false starts and shall
be capable of being drained automatically in flight so that fuel will drain clear
of all parts of the target, and manually through a drain valve while at rest so
that fuel will not be discharged on the target.
