PURGING THE FUEL SYSTEM
The diesel fuel system must be purged when starting
a new diesel engine for the first time, after prolonged
storage, the fuel tank is allowed to run dry, or when
the fuel filter and/or fuel lines have been loosened,
removed or replaced.
Purge the fuel system using one of the procedures as
follows:
PURGING FUEL SYSTEM USING A JUMPER WIRE
This method allows the fuel pump to run continuously
when purging the system.
1. Turn the ignition key to the “OFF” position.
2. Disconnect the white/red wire from the starter
solenoid.
3. Clip one end of a jumper wire to the EXC terminal
on the back of the alternator as shown in Figure
3D-5. (This terminal will have a green wire con-
nected to it.)
4. Clip the other end of the jumper wire to the “I” ter-
minal on the starter solenoid.
5. Open the bleeder plug located on top of the fuel
injector (see Figure 3D-6).
6. Turn the ignition key to the “ON” position (the fuel
pump will begin to pump). When the fuel pump is
pumping fuel only, the “thumping” sound will
become more of a “purring” sound, when this
occurs tighten the bleeder plug.
7. Turn the ignition key to the “OFF” position,
remove the jumper wire and reconnect the white
with red wire onto the starter solenoid.
PURGING FUEL SYSTEM WITHOUT
THE USE OF A JUMPER WIRE
Fuel system bleed may be accomplished using the
glow plug timer if no jumper wire is available.
1. Open the bleeder plug on top of the fuel injector
pump (see Figure 3D-6).
2. Turn the ignition key to the “ON” position. The fuel
pump will be activated for about 20 seconds until
the glow plug timer stops.
3. When the timer stops, turn the key to the “OFF”
position, then turn it back to the “ON” position, the
fuel pump will run again for approximately 20 sec-
onds, when the glow plug timer stops, turn the
key off again. Continue with this procedure until
the system is purged. When the fuel pump is
pumping fuel only, the “thumping” sound will be
more of a “purring” sound, when this occurs, tight-
en the bleeder plug.

WARNING
Failure to remove this wire may result in the
starter engaging causing the vehicle to move.
This movement could result in personal injury
and/or property damage.
