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
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
g) If the system is for JP-5 or other fuel that does
not have a static dissipater additive which provides a
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,
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
