9-28 Driving and Operating
5. Remove the fuel-resistant
container and properly dispose
of the contaminated fuel. To find
out how to properly dispose of
contaminated diesel fuel, see
What to Do With Used Oil
under Engine Oil Life System on
page 1010.
6. Install the fuel cap.
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 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 fuel
operated heater (FOH), or the
vehicle.
However, the engine and/or the fuel
operated heater (FOH) may not be
able to start until the fuel system is
primed and the air is removed.
