(4). Remove lower fuel supply hose.
(a). Remove vapor shroud box cover
assemblies from LH or RH intercon
nect tee fitting and crossfeed shut-off
valve (Ref. Section 28-00-00).
(b). Remove and discard lockwire.
Disconnect LH or RH vapor shroud
hose (21, 22) from LH or RH inter
connect tee fitting vapor shroud box
(3, 4) and fuel crossfeed shut-off
valve shroud box (11).
Residual Fluids
System Contamination
(c). Pull vapor shroud hose back and
disconnect end of LH or RH fuel
supply hose assembly (23, 24) from
LH or RH interconnect tee fitting (9,
10).
(d). Disconnect LH or RH fuel supply
hose assembly (23, 24) from crossfeed
shut-off valve (20).
(e). Remove bolt (25), washers (14) and
nut (15) and remove cushioned
support clamp (16). Remove fuel
supply hose assembly with vapor
shroud hose from aircraft.
NOTE: Note location of spacers on hose assem
bly before removal. Replace spacers in same
location upon installation.
(f). Slide LH or RH vapor shroud hose
(21, 22) off of LH or RH hose assem
bly (23, 24) and remove vapor shroud
spacers (17) from hose assembly.
B. Lower Fuel Supply Hoses and Shrouds
Installation
(Ref. Figure 419)
NOTE: This task is typical for LH and RH low
er fuel supply hoses and shrouds.
Consumable Materials

C230 Sealant, Electrically Conductive
C702 Lockwire
(1). Install lower fuel supply hose.
NOTE: Orient spacer slot down on horizontal
runs or aft on vertical runs.
(a). Install spacers (17) on LH or RH fuel
supply hose assembly (23, 24). Ref.
Figure 420 for spacer locations.
Sealing Compound (C207)
(b). Apply a fillet of sealing compound
(C207) at junction of spacer and hose.
Ensure that sealing compound does
not block holes in spacer.
(c). Slide LH or RH vapor shroud hose
(21, 22) over LH or RH hose assem
bly (23, 24) and spacers (17).
(d). Install LH or RH fuel supply hose
assembly (23, 24) and connect to LH
or RH interconnect tee fitting (9, 10).
Torque hose fittings (Ref. CSP-SPM).
(e). Connect LH or RH fuel supply hose
assembly (23, 24) to crossfeed
shut-off valve (20). Torque hose
fittings (Ref. CSP-SPM).
(f). Connect LH or RH vapor shroud hose
(21, 22) to crossfeed shut-off valve
vapor shroud box (11) and LH or RH
interconnect tee fitting vapor shroud
box (3, 4). Secure vapor shroud hose
with lockwire (C702).
(g). Install cushioned support clamp (16)
around fuel supply vapor shroud hose
at location of center spacer with bolt
(25), washers (14) and nut (15).
Torque nut (Ref. CSP-SPM).
