Fuel tank vent valves
E128985
Fuel tank ventilation is achieved by two fuel tank
vent valves. The fuel tank vent valves are integral
to the fuel tank and will prevent fuel loss from the
fuel tank if the vehicle becomes inverted.
Under normal working conditions, the pressure
within the fuel tank is controlled by allowing the
fuel vapor to vent through the fuel tank vent valves
to atmosphere. If the fuel tank becomes inverted,
the fuel tank vent valves close preventing fuel being
lost from the fuel tank.
If the fuel tank vent valves or the fuel vapor lines
connected to the vent valves become restricted,
vehicle performance will become impaired. The
inability of the fuel tank to substitute the fuel
demanded by the fuel charging system with air,
will create a negative pressure in the fuel tank
which will result in reduced fuel flow to the fuel
pump.

The fuel level sensor is located in the top of the
fuel tank and is retained by a fuel level sensor
locking ring and seal.
The fuel level sensor consists of a mechanical float
attached to a variable resistor card by means of a
rigid wire lever. The resistor card has two electrical
elements. One element is solid and one element
is a variable resistor. The resistance value created
by the resistor card is sent to the central junction
box (CJB) through a hard wired circuit. The CJB
distributes the information from the fuel level sensor
to the instrument cluster and the powertrain control
module (PCM) using the controller area network
(CAN) circuits.
The fuel level sensor resistor card can be
susceptible to contaminated fuel, which can affect
electrical continuity. This condition is normally
temporary and self-rectifying. If the fuel level sensor
has been removed, moving the rigid wire lever from
empty to full a minimum of 10 times will normally
be as effective as installing a new fuel level sensor.
The most common symptom of contamination
occurs after refuelling where the electrical contact
moves to an area of the resistor card which has
not been used for several days. This results in a

DESCRIPTION AND OPERATION
very slow movement of the fuel gauge pointer from
empty to full over approximately 15 minutes. In
more extreme cases where the resistor card
resistance is continuously outside the permitted
range for more than 33 seconds, a DTC will be set
in the CJB and the fuel gauge pointer will fall to its
key-off position. In all cases where the fuel level
sensor is suspected of being inoperative, worn or
damaged, the Worldwide Diagnostic System (WDS)
diagnostic procedures must be followed before any
parts are dismantled.
The base of the fuel level sensor is a chamber that
sits in the swirl bowl at the bottom of the fuel tank.
Built into the chamber is a filter element.
The fuel level sensor also incorporates a fuel jet
pump. The return fuel from the fuel charging
system is passed through a venturi in the jet pump
which causes a pressure drop across an open
orifice. This draws in fuel through the base of the
unit which then passes through the fuel supply
tube.

Water-in fuel sensor
Fuel is delivered through the fuel supply lines to
the fuel filter. The fuel filter cleans the fuel of water
and contaminants. Unused fuel is returned to the
fuel tank through the fuel cooler return line.
The fuel filter is also equipped with a water-in-fuel
sensor which measures the amount of water which
has collected in the fuel filter element.
Fuel Tank
The fuel tank is of a plastic construction and has
the capacity to hold 80 liters of fuel. The fuel tank
is secured to the vehicle by two metal support
straps bolted to the underside of the vehicle.

Fuel tank filler pipe
The fuel tank filler pipe incorporates a fuel tank
vent pipe. The fuel tank vent pipe is connected to
the top of the fuel tank and exits just below the top
of the fuel tank filler pipe. The fuel tank vent pipe
allows the displaced air above the fuel in the fuel
tank to escape without pushing the fuel entering
the fuel tank during refill back up the fuel tank filler
pipe.
This vehicle uses a lockable fuel filler cap.
The fuel filler cap is sealed to the fuel filler neck.
This is to prevent the escape of fuel vapor during
normal operation and to prevent fuel loss in the
event of a vehicle accident.
