INFORMATION FUEL HANDLING PRECAUTIONS
The following information provides basic precautions
which must be observed if fuel is to be handled safely.
It also outlines the other areas of risk which must not
be ignored.
This information is issued for basic guidance only, and
in any case of doubt, appropriate enquiries should be
made of your local Fire Officer or Fire Department.
Fuel vapour is highly flammable and in confined
spaces is also very explosive and toxic and when
diluted with air becomes a readily ignitable mixture.
The vapour is heavier than air and will always fall to
the lowest level. It can readily be distributed
throughout a workshop by air current, consequently,
even a small spillage of fuel is very dangerous.
Always have a fire extinguisher containingFOAM CO
2
GAS,orPOWDERclose at hand when handling fuel,
or when dismantling fuel systems and in areas where
fuel containers are stored.
WARNING: lt is imperative that the battery
is not disconnected during fuel system
repairs as arcing at the battery terminal
could ignite fuel vapour in the atmosphere.
Always disconnect the vehicle battery BEFORE
carrying out work on the fuel system.
Whenever fuel is being handled, transferred or
stored, or when fuel systems are being dismantled
all forms of ignition must be extinguished or
removed, any leadlamps used must be flame proof
and kept clear of spillage.
No one should be permitted to repair components
associated with fuel without first having had fuel
system training.Hot fuel handling precautions
WARNING: Before commencing any
operation requiring fuel to be drained from
the fuel tank, the following procedure must
be adhered to:
1.Allow sufficient time for the fuel to cool, thus
avoiding contact with hot fuels.
2.Vent the system by removing the fuel filler cap in
a well ventilated area. Refit the filler cap until the
commencement of fuel drainage.
Fuel transfer
WARNING: Fuel must not be extracted or
drained from any vehicle while it is
standing over a pit.
The transfer of fuel from the vehicle fuel tank must be
carried out in a well ventilated area. An approved
transfer tank must be used according to the transfer
tank manufacturer’s instructions and local regulations,
including attention to grounding of tanks.
Fuel tank removal
AFUEL VAPOURwarning label must be attached to
the fuel tank upon removal from the vehicle.
Fuel tank repair
Under no circumstances should a repair to any tank
be attempted.

The fuel pump is a self priming, wet type, two stage pump, which is emersed in fuel in the tank. It operates at all
times when the ignition switch is in position’II’. If the engine is not started, the ECM will’time-out’after three
minutes and de-energise the fuel pump relay.
The fuel pump assembly is retained with a locking ring and sealed with a rubber seal. The locking ring requires a
special tool for removal and refitment. The fuel gauge sender is integral with the fuel pump. The sender is
submerged in the fuel and is operated by a float which moves with the fuel level in the tank.

PANEL REPAIRS

INFORMATION BODY REPAIRS
Body shells are of riveted, bolted and welded
construction and are bolted to the chassis frame.
It is essential that design dimensions and strength are
restored in accident rectification. It is important that
neither structural weakness nor excessive local
stiffness are introduced into the vehicle during body or
chassis repair.
Repairs usually involve a combination of operations
ranging from straightening procedures to renewal of
either individual panels or panel assemblies. The
repairer will determine the repair method and this
decision will take into account a balance of economics
between labour and material costs and the availability
of repair facilities in both equipment and skills. It may
also involve considerations of vehicles down-time,
replacement vehicle availability and repair turn-around
time.
It is expected that a repairer will select the best and
most economic repair method possible, making use of
the facilities available. The instructions given are
intended to assist a skilled body repairer by expanding
approved procedures for panel replacement with the
objective of restoring the vehicle to a safe running
condition and effecting a repair which is visually
acceptable and which, even to the experienced eye,
does not advertise the fact that it has been damaged.
This does not necessarily mean that the repaired
vehicle will be identical in all respects with original
factory build. Repair facilities cannot always duplicate
methods of construction used during production.
The panel repairs shown in this section are all based
on a 110 Station Wagon. Therefore all illustrations
and text relate only to this model. Although certain
areas of the vehicle, such as the front end, are
relevant to all models.
Operations covered in this Manual do not include
reference to testing the vehicle after repair. It is
essential that work is inspected and suspension
geometry checked after completion and if necessary a
road test of the vehicle is carried out, particularly
where safety related items are concerned.Where major units have been disconnected or
removed, it is necessary to ensure that fluid levels are
checked and topped up when necessary. It is also
necessary to ensure that the repaired vehicle is in a
roadworthy condition in respect of tyre pressures,
lights, washer fluid etc.
Body repairs often involve the removal of mechanical
and electrical units as well as associated wiring.
Where this is necessary use the relevant section in
this manual.
Taking into consideration the differences in body
styles, steering and suspension systems as well as
engine and suspension layouts, the location of the
following components as applicable to a particular
vehicle is critical:
Front suspension upper damper
mountings.
Front suspension or sub frame mountings.
Engine mountings on RH and LH chassis
longitudinals.
Rear suspension upper damper mountings.
Rear suspension mountings or lower
pivots.
Steering rack mountings.
Additional points which can be used to check
alignment and assembly are:
Inner holes in crossmember - side - main
floor.
Holes in valance front assembly.
Body to chassis mounting holes.
Holes in rear floor.
Holes in rear lower panels or extension
rear floor.
Fuel tank mountings.
Apertures for windscreen, backlight, bonnet and doors
can be checked by offering up an undamaged
component as a gauge and also by measuring known
dimensions.See BODY DIMENSIONS section.
