Fuel Tank and Lines (10.01)
Fuel (10.00)
May 2007 Workshop Manual 10-1-3
Fuel Tank
The fuel tank incorporates a single filler neck and check valve, internal fuel pump, internal fuel filter, a sender unit and an
‘on board refuelling vapour recovery’ system.
Fuel Pumps

)XHO3XPS
The modular fuel pump is immersed in the base of the fuel
tank. The pump can deliver up to 150 litres/hour. The in-
tank fuel line connects to the external line using a quick-fit
connector in the base of the fuel tank. During normal running, pressu
rised fuel from each fuel
pump passes from the tank, through an 3 micron in-tank fuel
filter to one of the two fuel rails on the engine.
Fuel temperature is measured on the primary fuel rail. If fuel
temperature becomes excessive, the fuel pressure is
increased to prevent fuel vaporisation (boiling).
Fuel pressure is measured by sensors on each fuel rail. The
fuel pressure to each rail is regulated as required by
continuously changing the run speed of the associated fuel
pump. Maximum pressure in the system is limited to 5.3 bar
by in-tank pressure regulators.
A constant head of fuel is maintained in the fuel pump
modules to ensure that the pumps cannot run dry in a ‘low
fuel’ situation.

Storing Refrigerant
Handling Insufficient Refrigerant Level
Handling Compressor Oil
Refrigeration Cycle
Operation
1. The Compressor (1) dr aws low pressure, low
temperature, refrigerant vapour from the evaporator (5)
and compresses it, raising th e refrigerant pressure and
temperature.
2. This high pressure, hot, refrigerant vapour enters the condenser (2), where it is cooled by the flow of ambient
air and changes state into a cooler, high pressure liquid.
3. From the condenser, the liqu id passes into the receiver
drier (3) which has three functions:
• Removes moisture from the refrigerant using a desiccant
• Filters the refrigerant to remove system contaminants
• Stores the refrigerant to cope with varying system refrigerant demands
4. The filtered liquid refrigerant, still at high pressure, then enters the expansion valve (4). Here it passes through a
controlled orifice and emerges as an atomised liquid
spray. This has the effect of reducing the refrigerant
pressure and temperature. The cold refrigerant spray
now flows into the evaporator (5).
5. As refrigerant passes through the evaporator core, it cools the incoming airflow. Heat is absorbed by the
refrigerant, during this process and it once again changes
state, from an atomised cool liquid into a vapour. The
refrigerant vapour then returns to the compressor for the
cycle to be repeated.
An automatic safety valve is incorporated in the compressor,
which will open if the system pressure rises above 41 bar.
The valve will reseat when the pressure drops below 27,6
bar. When the safety valve is open, the compressor will 'free
Warning
The refrigerant container is highly pressurized. If it is subjected to high heat, it could explode, scattering metal fragments and liquid refrigerant that can
seriously injure personnel. Store refrigerant at
temperatures below 40
oC (104 oF).
Caution
If an insufficient refrigerant level is detected while
troubleshooting, do not char ge (add) the refrigerant.
Because an accurate amount of refrigerant cannot be
determined from the pressure indicated on the
recovery / recycling / rechar ging unit, never charge the
refrigerant.
Caution
If there is too much or to o little refrigerant from the
refilling, there may be secondary problems such as
damage to the refrigerant cycl e parts, or a decrease of
cooling performance. Therefore, if it is determined that the refrigerant level is insufficient, completely remove refrigerant from the refriger ant cycle and refill with
refrigerant to the specified amount.
Caution
Use only ND8 compressor oil for this vehicle. Using a PAG oil other than DENSO OIL8 compressor oil will damage the A/C compressor.
Caution
Do not spill the ND8 compressor oil on the vehicle. A drop of compressor oil on the vehicle surface can
damage the paint work. If oil gets on the vehicle, wipe it off immediately.
Caution
ND8 compressor oil has a high moisture absorption
efficiency. If moisture mixe s with the compressor oil,
the refrigerant system could be damaged. Ensure caps
are installed immediately afte r using the compressor oil
or removing refrigerant system parts to prevent moisture absorption.

Leaks
Faults associated with low refrigerant charge weight and low pressure may be caused by leakage. Leaks traced to
mechanical connections may be caused by torque relaxation or joint face contamination. Evidence of oil around such
areas is an indicator of leakage.
Leak Detection
Fluorescent Tracer Dye - A fluorescent tracer dye is incorporated into th e refrigeration system and can be checked for
non-apparent leaks by scanning with a high intensity ultraviolet lamp. The location of leaks can be pinpointed by the bright
yellow glow of the tracer dye.
Automatic Refrigerant Leak Detector - (various manufacturers) Hand-held, portable, battery operated leak detector.
Place in and around A/C system to detect refrigerant leaks.
System Pressure Fault Classification
This table should be used in conjunction with the graphical representations of 'High side' pressure / ambient temperature
and 'Low side' pressure / evaporator temperature. Caution
Observe ALL safety precautions associ ated with ultraviolet equipment.
If erratic or unusual gauge movements occur, check the equipment against known Recovery / Recycling / Recharging unit
gauges.
