18.
At upper end of manifold (14) on both main tanks
(33) remove plates (21) and install blanking
plates (18) as follows:
a.
Remove eight nuts (11), bolts (13), and
washers (12). Move manifold (14), plates (18
and 21), and gaskets (15 and 16) forward.
Gaskets and plates must be installed
in correct order. Otherwise, damage
to fittings will result.
b.
Remove plate (21). Install gasket (17) and
plate (18) (APP E17), on lower fitting (19).
Install gasket (20) and plate (18) on upper
fitting (22). Move manifold (14) and gaskets
(15 and 16) aft. Install eight bolt (13) nuts
(11), and washers (12).
19.
Repeat steps 15 and 16. If gage reads 120 psi,
go to step 21. If gage reads less than 120 psi,
go to step 20.
20.
Check pressure refueling tubing and fittings
connecting intertank areas through fuselage.
Refer to TM 55-1500-204-291.
21.
At right main tanks manifold (14), remove eight
nuts (11), bolts (13), and washers (12). Slide
manifold (14), plates (18 and 20), and gaskets
(15 and 16) forward. Repeat steps 9 thru 12.
22.
Repeat steps 15 and 16. If gage reads 120 psi,
go to step 24. If gage reads less than 120 psi,
check left main tank (33) for leak. Install blanking
plates (18) on right main tank manifold (14), as
in step 18.
23.
At left main tank manifold (14), remove eight
nuts (11), bolts (13), and washers (12). Slide
manifold (14), plates (18), and gaskets (15 and
16) forward. Repeat steps 9 thru 12.
24.
Repeat steps 15 and 16. If gage reads 120 psi,
go to step 25. If gage reads less than 120 psi,
check right main tank (33) for leaks.
