MAIN TANK (NO. 2 SYSTEM) FUEL LEVEL SHUTOFF VALVE INSTALLATION
Remove plugs from the assembly of manifold
(20), cross fitting (21), and elbow (22). Align the
assembly, with two gaskets (18), with the two
tank fittings and lower fitting (23).
Install four bolts (17), washers (16), and nuts (15)
at the top flange of manifold (20).
Position the clip of hose clamp (19) against
the lower flange of manifold (20) at the lower
outboard hole. Install four bolts (17), washers
(16), and nuts (15).
Do not use a strap wrench or
overtighten the ring nut. Failure may
Hand tighten the lower ring nut on elbow (22)
on fitting (23). Lockwire the lower ring nut to the
upper ring nut. Use lockwire (E231).
When connecting fuel hoses to the
forward access panel, do not allow the
fittings to turn. If they turn, the fittings
can fail and cause fuel blockage.
Remove the plug from hose (25). Install conical
seal (24) in the hose fitting. While holding the
manifold fitting with a wrench, connect the hose
to the inboard fitting of manifold (20).
Tube (30) is not symmetrical. Make
sure the upper nut on the landing
gear mount remains accessible when
installing the tube.
Aft gasket (29) has a larger center
hole than the forward gasket.
Position gaskets (29) and tube (30) between
forward tank adapter (31) and cross fitting (21).
Slide the forward fitting on the cross fitting
forward to hold the tube and gaskets in place.
Install four bolts (28), washers (27) and nuts (26)
at each end of the tube. Make sure the heads of
the bolts face each other.
