assemblies of stainless steel components. Additive injection
is not normally performed at the installation level. Consult
Service Headquarters for guidance as to which additives must
be included.
4.9.1
Plus 100 Additive. Additive packages to raise the
auto ignition point of jet fuel by 100 degrees F also act as
surfactants which will disarm the filter/separators. There,
it is important this additive package is introduced only at
refueler fill stands, downstream of the filter/separator,
prior to entering the truck. In addition, care must be taken
to ensure there is no capability in the design for plus 100
fuel to be introduced back into storage. Because the plus 100
fuel is being used on a limited basis at designated air
stations, the command fuels engineer will provide direction as
to locations where it is permitted.

DEFUELING SYSTEMS. Because of degradation of flash
point, ensure that JP-5 direct fueling systems are not capable
of defueling an aircraft back into operating storage.
Accomplish defuel by the use of tanker vehicles or dedicated
defuel tanks. Provide JP-8 hydrant systems with defuel
capability.
