striker and the-fuel cap stowage magnet.
The fuel bowl, retained around the filler neck by a clip, containing a drain tube filter located over the mating drain tube,
is rubber moulded onto a steel armature and fitted to the BIW decking panel by five M5 nuts.
The fuel lid latching assembly fitted to the metal armature of the fuel bowl by an M5 nut, includes the locking pin and
the operating actuator.
The actuator operates from the central locking system driven by the security and locking control module
(SLCM).
The fuel tank, mounted across thevehicle behind the passenger compartment rear bulkhead, is held in position by two
retaining straps, tightened by two M5 fixing arrangements.
The fuel tank of AJ16 engined vehicles contains one fuel pump, supplying fuel to the normally aspirated engine and
two fuel pumps, supplyingfuel to the supercharged engine. They are regenerative turbine pumps supplied by
Nippon- Denso. Nominal operating pressure is 3 bar (3.7 bar for supercharged engine) above the manifold depression and
pump delivery is 90 litredhour minimum at 13.2 volts, 3 bar outlet pressure. The pump(s) draw a nominal current of 7 amperes at 13 volts, 3 bar outlet pressure, ambient temperatures. Built in to the pump assembly is a over-pressure
relief valve which blows at 4.5 - 8.5 bar.
Fuel is drawn by the pumps from the fuel tank and is then supplied to the fuel rail via a
70 micron filter and the fuel
feed line connected in series by fuel filter.
The amount of fuel being injected into the engine
is controlled by the fuel injectors combined with the engine control module (ECM). - Any excessive fuel flowing through the system, is returned to the fuel tankvia the fuel regulator valve mounted on the
fuel rail, the fuel return line and the check valve also located inside the tank.
The two filters prevent contaminants from entering the fuel rail and possible damage to the fuel injectors, the engine,
the pump and the underfloor filter.
The fuel pumps are switched on and off by relays controlled by the engine control module
(ECM).
The second fuel pump for the supercharged engine operates only in the higher speed range, switching on at 4000rpm and off at 3200rpm.
The fuel lines are made up of an assembly, combining steel under floor pipes and flexible conductive anti-permeation
tubing. In orderto perform speedy remove and refit operations, the underfloor steel lines are linked through the engine
bay bulkhead to the flexible tubing, leading to the fuel rail and the fuel regulator by using positive sealing, quick-fit
type connectors. The same type connectors, are used to connect the fuel feed and return line to the fuel tank.
Connectors used inside the engine bay are of different sizes tocorrespond with the difference in pipe diameter, whereas
the connectors for the feed and return lines at the fuel tank are the same size.
Except for the return line connector at the fuel tank, two release tools, one for each size of connector are required to
release all remaining connectors.

5.1.2 GENERAL DESCRIPTION
m: WORKING ON THE FUEL SYSTEM MAY RESULT IN FUEL AND FUEL VAPOUR BEING PRESENT IN THE
ATMOSPHERE. FUEL VAPOUR IS EXTREMELY FLAMMABLE, HENCE GREAT CARE MUST BE TAKEN WHllST WORKING ON THE FUEL SYSTEM. ADHERE STRICTLY TO THE FOLLOWING PRECAUTIONS:
DO NOT
SMOEIN THE WORK AREA.
DISPLAY 'NO SMOKING
' SIGNS AROUND THE AREA.
ENSURE THAT A
CO2 FIRE EXTINGUISHER IS CLOSE AT HAND.
ENSURE THAT DRY SAND
IS AVAILABLE TO SOAK UP ANY FUEL SPILLAGE.
EMPTY FUEL USING SUITABLE FIRE
PROOF EQUIPMENT INTO AN AUTHORIZED EXPLOSIOWROOF
CONTAINER.
DO NOT EMPTY FUEL
INTO A PIT.
ENSURE THAT WORKING AREA
IS WELL VENTILATED.
ENSURE THAT ANY WORK ON THE FUEL SYSTEM
IS ONLY CARRIED OUT BY EXPERIENCED AND WELL
QUALIFIED MAINTENANCE PERSONNEL.
The fuel filler assembly, supplied complete with serviceable lid, hinge and hinge spring, is fixed to the Body-in-White
