When The Fuel Has Run Out (Bleeding The Fuel System) - Mitsubishi Fuso FK/FM 2006 Owner's Manual

4. After the above connections have been com-
pleted, start the engine of the vehicle with the
booster battery and let it run at an RPM slightly
higher than idling speed. Then, attempt to start
the engine of the vehicle with the dead battery.
If the engine starts with difficulty because of cold
weather or a dead battery, let it draw a charge
for several minutes from the vehicle from which
you are receiving the boost before attempting to
turn over the engine.
5. After the engine of the vehicle with the dead bat-
tery has been started, disconnect the booster
cables by reversing the order of connection.
When the vehicle runs out of fuel and the engine
stalls, when the fuel filter element has been
replaced, or when the water in the fuel filter has
drained, air that has entered the fuel system pre-
vents the engine from being started even after the
engine is refueled.
In these cases, bleed the fuel system by performing
the following steps.
WARNING
A fire could result if there is a fuel leak or if
spilt fuel is not removed. Always wipe off
spilt fuel after air bleeding. Also be sure to
check for fuel leakage.
CAUTION
The fuel injection system may fail if the engine
stops due to lack of fuel.
1. Loosen one of the air bleeder plugs
filter.
NOTE:
Use whichever of the two air bleeder plugs is the
most convenient; both plugs provide the same
effect.
2. Cover the pipe portion of the loosened air
bleeder plug with a cloth and operate the prim-
ing pump
NOTE:

Alternatively, connect a hose with an inside diame-
ter of 8 mm (0.31 in.) to the pipe portion of the air
bleeder plug in order to prevent fuel from splashing.
Use a transparent hose so you can easily check for
air bubbles in the fuel.
3. Fuel containing air bubbles will flow out of the
pipe portion. Continue pumping until fuel no
longer contains air bubbles.
