a. General.
The Hoseline outfit is designed for temporary use only, and should be retrieved and repacked after
need for outfit has been met. Before packing outfit, all residual fuel must be removed, and all fuel vapors and air
must be evacuated so that hose will collapse for repacking into flaking boxes. This section details the use of the
displacement and evacuation kit.
b.
Fuel Displacement.
(figure 2-10) Residual fuel in hoseline will be removed using the following procedures.
(1)
(2)
(3)
(4)
(5)
(6)
(7)
(8)
(9)
W A R N I NG
Do not smoke, carry an open flame, or use any heat-producing device near
hoseline during fuel displacement and vapor evacuation operations.
N O T E
• Fuel flow from pump to supply.
• When breaking hoseline connections, ensure fuel is drained in a suitable
container.
Remove hose clamp (1) from repair kit and apply it to discharge hoseline (2) at pump end. Ensure that
clamp is positioned 12 inches (305 mm) from coupling end.
Disconnect discharge hoseline at pump end.
Attach ball inlet (3), with ball (4) installed, to hoseline (2) at pump end using a pipe coupling clamp (5) and
gasket (6) and secure with bolts (7) and nuts (8).
Apply a second hose clamp (9) to opposite end of hoseline (2). Close supply and shut off valve and
disconnect hoseline at supply connection (10).
Connect ball receiver (11 ) between supply end of hoseline and supply connection (10) using pipe
coupling clamps (12) and gaskets (13) and secure with bolts (14) and nuts (15).
Connect an air compressor to ball inlet (3) and apply 25 to 30 psi (1.8-2.0 kg/cm2) to hoseline.
W A R N I NG
Stand clear of receiver while displacement procedure is in process. Hoseline may
jump when ball arrives at receiver.
Remove both hose clamps (1) and (9) and open supply shutoff valve. The ball will move through hose
displacing any residual fuel. A sound will be heard when ball reaches receiver.
NOTE
If ball gets stuck or binds, it maybe necessary to ease any possible hoseline kinks
or restrictions. It maybe necessary to increase air pressure. Do not exceed 150
psi (10.5kg/cm2).
Shut off air compressor when ball reaches receiver and close supply shutoff valve.
Disconnect hoseline and remove ball receiver (11) and ball (4). Do not remove ball inlet (3).
