MIL-HDBK-1022A
Eliminate covered hose storage rack if off-load rack is to be
covered. Ensure that all swivels are non-lubricated aluminum
or stainless steel in-line repairable type. Consult with
activity to verify the need for hoses. At some activities,
the fuel hauling contractor provides the hoses.
c) Equip each tank truck off-loading position with
an automatic, self-monitoring ground verification unit with a
lockable bypass. If grounding is not verified and there is an
off-loading pump dedicated to that position, ensure the unit
prevents the pump from starting. If the pump is not
dedicated, ensure an alarm sounds if the off-loading valve is
opened prior to grounding verification. Include a separate
grounding reel to accommodate vehicles without grounding
equipment. (This unit is optional on Air Force projects.
Contact the Service Headquarters.)
d) Provide fuel sampling connections for collecting
test samples.
e) Provide pressure gauges on both sides of all
strainers or a differential type gauge across the strainer.
Where a strainer is upstream of a pump, the pump suction gauge
may function as the strainer downstream gauge.
f) Provide a compound (pressure/vacuum) gauge on the
inlet side of pumps and a pressure gauge on the outlet side of
pumps.
g) If the system is for JP-5 or other fuel that does
not have a static dissipater additive which provides a
conductivity level greater than 50 conductivity units (50
picosiemens per meter), and a 30-second retention time is not
provided between filter/separator and receiving tank, provide
a relaxation tank downstream of filter/separator to ensure a
combined 30-second retention time (time in the tank and time
in the piping).
h) Provide basket strainers upstream of pumps,
except positive displacement pumps.
i) Provide a combination flow control and non-surge
check valve on all off-load pumps except positive displacement
types. Provide flow control through a hydraulically operated
