Fuel tubes must be clamped and routed so
they do not contact each other or any
other component during engine operation,
or damage to equipment could result.
Position six fuel tubes (2) on engine (8) and
install two screws (6) in brackets (7). Tighten
screws to 216 lb-in. (24.4 N·m).
Install, but do not fully tighten, nuts in
Step (5) below. Nuts will be fully
tightened in Step (7).
Install six fuel tubes (2) on fuel injection
pump (5) with nuts (4).
Position six fuel tubes (2) on fuel injectors (3)
and loosely install nuts (1). Tighten nuts (4)
to 18 lb-ft (24 N·m).
· To prevent danger of fire caused by fuel
spilling on hot exhaust manifold, do not
bleed fuel tubes if engine is hot. Failure to
observe this precaution could result in injury
or death to personnel.
· Safety glasses must be worn when
working on pressurized systems.
Failure to observe this precaution
could result in serious injury.
Ensure auxiliary fuel shut-off switch is in the ON position (refer to TM 10-3939-673-10).
Bleed fuel tubes (2) at fuel injectors (3).
Crank engine until fuel is flowing from all six fuel tubes (2) at injectors (3). Tighten six nuts (1).
Bleed fuel tubes (2) at injectors (3), one at a time, until engine starts and runs smoothly. Repeat Steps (7)(c)
through (7)(e) for each fuel tube (2) as required.
Loosen nuts (1).
Crank engine until fuel flows from tube (2).
