refitting
Note: Observe the precautions in Section 1
before working on any component in the fuel
system.
Removal
1 Before the tank can be removed, it must be
drained of as much fuel as possible. To avoid
the dangers and complications of fuel
handling and storage, it is advisable to carry
out this operation with the tank almost empty.
Any fuel remaining can be drained as follows.
2 Disconnect the battery negative lead.
3 Using a hand pump or syphon inserted
through the filler neck, remove any remaining
fuel from the bottom of the tank.
4 Chock the front wheels then jack up the
rear of the car and support it on axle stands
(see "Jacking and vehicle support").
5 Either remove the complete exhaust system
or, on later models, release the support band
on the silencer, and lower the system using a
3
jack under the tailpipe.
6 Release the handbrake cables from their
fuel tank and other guide sleeves - there is no
need to disconnect the cables.
7 Unbolt and remove the heat shield.
8 Disconnect the wiring from the fuel gauge
sender unit.

9 Unscrew the mounting and safety strap
bolts and nuts, then lower the tank - at the
same time disconnecting the filler, breather
and supply hoses.
10 If the tank is contaminated with sediment
or water, remove the fuel gauge sender unit as
described previously and swill the tank out
with clean fuel. The tank is moulded from a
synthetic material and if damaged, it should
be renewed. However, in certain cases it may
be possible to have small leaks or minor
damage repaired. Seek the advice of a dealer
or suitable specialist concerning tank repair.
