FUEL LINE BLEEDING
NOTE: Fuel line bleeding is necessary if fuel injection pump is
replaced, fuel filter/water separator is not filled with
diesel fuel before installing or vehicle ran out off fuel.
Bleed high-pressure fuel lines if connections are loosened or
replaced. If engine has not been operated for an extended
time, bleed fuel lines before next initial engine start-up.
WARNING: DO NOT bleed fuel lines on a hot engine, as high exhaust
temperatures may cause a fire. Carefully bleed fuel lines, as
fuel is under extremely high pressure and could penetrate
skin. Use safety goggles and protective clothing when
bleeding fuel lines.
1) Loosen banjo bolt holding low-pressure fuel supply line to
side of fuel injection pump. Wrap a towel around banjo fitting to
catch fuel. Crank engine quickly and release key before engine starts.
This will operate fuel transfer pump for about 25 seconds.
2) If fuel is not present at fuel supply line after 25
seconds, turn ignition off. Repeat engine crank procedure until fuel
is present at fuel supply line. Tighten banjo bolt at fuel supply line
to specification. See TORQUE SPECIFICATIONS.
CAUTION: Ensure parking brake is applied and transmission is in
Neutral before bleeding fuel injection pump or high-pressure
fuel lines. DO NOT operate starter for more than 30 seconds
when bleeding fuel injection pump or high-pressure fuel
lines. Allow 2-minute intervals between starter operations.
3) To bleed air from fuel injection pump, ensure parking
brake is applied and transmission is in Neutral, as engine may start
when operating starter to bleed air from fuel injection pump. Operate
starter for 30 seconds to bleed any trapped air in fuel injection
pump.
4) To bleed high-pressure fuel lines, ensure parking brake is
applied and transmission is in Neutral, as engine may start when
operating starter to bleed high-pressure fuel lines. Loosen high-
pressure fuel line nut at fuel injector.
5) Operate starter until steady fuel flow exists at high-
pressure fuel line. Tighten high-pressure fuel line nut to
specification. See TORQUE SPECIFICATIONS. Start engine. Repeat
procedure on each high-pressure fuel line until engine operates
smoothly.
FUEL FILTER/WATER SEPARATOR & WATER-IN-FUEL SENSOR
NOTE: Vehicle also contains an in-tank fuel filter located on
bottom of fuel tank module. For servicing procedure, see FUEL
TANK MODULE & IN-TANK FUEL FILTER under FUEL SYSTEM.
NOTE: When fuel filter/water separator is being replaced,
manufacturer recommends cleaning the pre-filter. See FUEL
HEATER under FUEL SYSTEM for servicing of pre-filter.
Removal
1) Ensure engine is off. Place drain pan below drain tube at
fuel filter/water separator. See Fig. 3. Rotate handle on drain valve
forward, toward front of vehicle to DRAIN position. Drain valve is
located near top of fuel filter/water separator. See Fig. 3. Once fuel
is drained from fuel filter/water separator, rotate handle on drain
valve back to CLOSE position.
Page 932 of 1691
Removal
1) Raise and support vehicle. Disconnect negative battery
cables. Drain fuel tank. Remove fuel tank filler tube bolts from body.
Support fuel tank with transmission jack. Remove fuel tank straps and
heat shields (if equipped).
2) Slightly lower fuel tank for access to fuel lines and
electrical connector at fuel tank module. Disconnect electrical
connector and fuel lines at fuel tank module. See Fig. 7. Use proper
procedure when disconnecting fuel lines. See FUEL LINE DISCONNECT
FITTINGS under FUEL SYSTEM.
NOTE: Information for servicing of in-tank fuel filter is not
available from manufacturer. If necessary to service in-tank
fuel filter, consult parts department to verify if filter may
be replace without replacing fuel tank module.
3) Note direction of fuel line connections on fuel tank
module for installation reference. Using Spanner Wrench (6856),
unscrew plastic fuel tank module lock nut from fuel tank. Remove fuel
tank module and gasket from fuel tank. Inspect in-tank fuel filter for
damage.
Installation
1) Using NEW gasket, install fuel tank module in fuel tank.
Install plastic fuel tank module lock nut finger tight. DO NOT tighten
plastic fuel tank module lock nut at this time.
2) Position fuel tank module so fuel line connections and
electric connection are facing toward driver's side of vehicle. This
must be done to prevent float on fuel gauge sending unit from
contacting fuel tank.
3) Once fuel tank module is properly positioned, tighten
plastic fuel tank module lock nut to specification. See TORQUE
SPECIFICATIONS.
4) Install fuel lines on fuel tank module using proper
procedure. See FUEL LINE DISCONNECT FITTINGS under FUEL SYSTEM.
Install electrical connector on fuel tank module. Reinstall fuel tank.
Tighten fuel tank strap nuts to specification. See TORQUE
SPECIFICATIONS. Reconnect negative battery cables.
