(3) Squeeze excess fuel from the tank by
rolling the ends of the tank toward the drain fitting.
(4) Open the drain fitting control valve to
allow the remaining fuel to dram from the tank,
d. Draining (Tank, NSN 5430-00-268-8187).
(1) remove the filler and discharge elbow.
(2) Beginning at the opposite end of the tank,
lift the tank slightly, forcing any residual fuel toward
the open fitting.
The sludge which accumulates in the bot-
tom of storage tanks gives off explosive
vapors and can cause lead poisoning
through inhalation. When cleaning tanks,
ample ventilation must be provided to carry
off harmful fumes. Residual sludge must be
buried in a location where it is not likely to
be uncovered.
e. Repacking. When repacking for storage, the
following procedure is used:
NOTE
Care should always be taken not to damage
tank by rough handling or careless storage.
(1) Drain fuel from tank (para. 2-15 b).
(2) Dry out tank by purging with air pressure.
Use a line pressure of 50 psi (3.40 Atmospheres)
maximum.
(a) Insert air hose through the filler and
discharge adapter opening at one end of the tank.
(b) Place rags around air hose at the fitting
to prevent air escaping between hose and fitting.
(c) Blow air into tank until tank is 3 feet
(0.914 meters) high.
(d) Remove dust cap from the vent fitting
and allow the air to vent for a period of 30 minutes.
(e) Turn off air supply and remove hose
and rags.
(3) Remove the filler and discharge elbows
from the filler and discharge adapters and install the
dust caps on the adapters.
(4) Remove the dust cap (fig. 2-2), from the
vent fitting adapter to allow trapped air to vent. Fold
the tank from the sides toward the middle. Brush off
any stones or debris which cling to the folded tank.
Roll the tank from the end opposite the drain fitting.
(5) Hose assembly openings should be
plugged with any suitable material to keep them dirt
free.
(6) Return components to their boxes and the
tank to its shipping container. Component boxes
should be placed in the shipping container with the
tank.
(7) If the original component containers are
no longer available, all loose items must be padded or
wrapped before storing with the tank in order to avoid
chafing the tank during prolonged storage or during
transportation.
(8) Care should always be taken to avoid
damaging the tank through rough handling or careless
storage.
