1994 JAGUAR XJ6 fuel cap release

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.

A5.3 GENERAL INFORMATION
The following information detailsthe purpose and function of the system components irrespective of individual variant
features.
A5.3.1 Locking:
Central locking
A traditional central locking application, such that when the driver's / passenger's door is locked / unlocked using the
door key all four doors lock / unlock simultaneously.
1ynfe: Locking operations will only take place when all doors are completely closed.
Remote central locking
Automatic locking / unlocking, activated by the larger of the two key fob buttons.
1ynfe: Locking operations will only take place when all doors are completely closed.
Deadlocking
A means of securing door locks so that they cannot be opened using the interior release mechanism, and arming the
security sensing system, using the door key or remote transmitter
Two-otage unlocking
A key / remote operated unlocking procedure which releases driver's door and fuel filler cap locks only, initially, and
then releases all other doors and the luggage compartment locks.
Drive-away locks
Automatic locking of all doors, and luggage compartment (but not fuel filler cap), when gear selector is moved away
from 'Park' and the ignition switch is in position II, providing all doors are closed.
Central lock / unlock, all close
Automatic locking of all doors and luggage compartment by operation of the fascia mounted central locking switch.
Continued switch operation causes closure of sliding roof and open windows.
Interior trunk lid release
Trunk lid unlocking from fascia mounted switch.
Flush sill buttons / intrusion override
Sill buttons fitted flush to door trim panel to prevent unauthorized override operation, buttons are latched in position
when deadlocking is applied.
