MIL-HDBK-1022A
b) In piping used for off-loading only, provide a
non-surge check valve near the base of the marine loading arm
to minimize loss of fuel in case of damage to the loading arm.
In piping used for both loading and off-loading, equip the
check valve with a manual override.
c) Provide block valves on the aboveground piping at
each barge or tanker off-loading and loading connection.
d) Provide block valves near the shoreline of a
submerged pipeline to offshore moorings.
e) Provide block valves on the inlet and outlet
connection of each line strainer, filter/separator, meter,
automatic valve, and other equipment that requires periodic
servicing.  One inlet valve and one outlet valve may be used
to isolate more than one piece of adjacent equipment which are
connected in series.
f) Provide thermal relief valves around all block
and check valves that can isolate a section of piping.
g) Do not use gate valves in fueling systems.
5.8.8
Pressure or Pressure/Vacuum Gauges.  Use glycerin-
filled or silicone-filled pressure gauges of range and dial
size, as necessary, but not less than 0 to 160 psig (0 to
1100 kPa) pressure range and 4-inch (100 mm) diameter dial.
Also:
a) Use pressure gauges upstream and downstream of
strainers, filters/separators, and cartridge-type fuel quality
monitors.  A differential pressure gauge may be used in lieu
of gauges on each side.
b) Install compound (pressure/vacuum) gauges on the
suction side of each pump at fuel storage tanks.
c) Provide a lever handle gauge cock and pressure
snubber in each pressure gauge connection.
d) Provide a pressure gauge on each side of the
pipeline shutoff valve at the shore end of each pier-mounted
pipeline.  Provide the indicating pointer with a high-
pressure-reading tell-tale indicator suitable for reporting
