9-30 Driving and Operating
7. For pickup models, start the
engine and let it run for a few
minutes. If the engine stalls, the
fuel system may need to be
primed. While draining the water
from the fuel filter, air may enter
the fuel system. If air has
entered the fuel system, the fuel
system will need to be primed.
For van models, start the engine
and let it run for a few minutes.
If the WATER IN FUEL SERVICE
REQUIRED message/warning light
comes on again after driving a short
distance or the engine runs rough or
stalls, a large amount of water has
probably been pumped into the fuel
tank. The fuel tank should be
purged.
Fuel Priming
In order for the fuel system to work
properly, the fuel lines must be full
of fuel and contain no air. If air gets
into the fuel lines, it will be
necessary to prime the fuel lines to
eliminate air before operating the
vehicle and the fuel operated
heater (FOH).
If air is in the fuel lines, one of the
following may have happened:
. The vehicle ran out of fuel.
. The fuel filter was removed for
servicing or replacement.
. The fuel lines were removed or
disconnected for servicing.
. The fuel filter water drain valve
was opened while the engine
was running.
. The fuel operated heater (FOH)
pump and FOH fuel lines were
removed or disconnected for
servicing.
If one or more of the above occur, it
is very likely that air has entered the
fuel system and priming the fuel
system is needed before operating
the vehicle. Air in the fuel lines does
not harm the engine, the FOH,
or the vehicle.
However, the engine and/or the
FOH may not be able to start until
the fuel system is primed and the air
is removed.
To Prime the Vehicle (Pickup
Models)
The vehicle is equipped with a
priming pump which is part of the
engine mounted fuel filter. The
priming pump is hand operated and
is designed to bring fuel to the
engine to eliminate any air in the
fuel lines. To prime the engine:
1. Correct the condition that
caused the loss of prime by
making sure there is fuel in
the tank.
2. Make sure the fuel filter has
been installed and properly
tightened.
3. Make sure the fuel lines are
properly connected and the fuel
filter is cool enough to touch.
4. Remove any dirt from the fuel
filter head and vent valve by
wiping with a cloth.
