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.

Symptom (7)DescriptionPossible Cause
Air from vents not cold enough. Magnetic clutch operates but A/
C system malfunctions. • Drive belt fault
• Fault in blower unit or condenser
• Fault in Receiver / Drier or expansion valve
(valve closes too much)
• Fault in refrigerant lines
• A/C compressor system fault, insufficient compressor oil
• Over filling of compressor oil, fault in expansion valve or A/C unit air mix link system
Symptom (8)Possible Cause
No cool air. Magnetic clutch does not
operate. • Fault in PCM A/C cut control system
• Fault in A/C Module
• Fault in refrigerant pressure switch
• Fault in PCM (A/C signal)
• Fault in PCM (IG1 signal)
• Fault in A/C compressor
•Fault in A/C relay
• Fault in Evaporator Temperature Sensor
Shake the wiring harness and connectors wh ile performing the inspection to discover whether poor contact points are the
cause of any intermittent malfunctions. If there is a problem, check to make sure connectors, terminals and wiring harnesses
are connected correctly and undamaged.
Symptom (9)Possible Cause
Noise while operating A/C
system. Noise from magnetic clutch, A/C
compressor, hose or refrigerant
line. • Magnetic clutch operation noise
• A/C compressor slippage noise
• Hose or refrigerant line interference noise
