7Fuel tank - removal,
examination and refitting
4
Note: Refer to Section 2 before proceeding
Removal
1Disconnect the battery negative lead.
2Siphon out any remaining fuel in the tank
through the filler pipe. Siphon the fuel into a
clean metal container that can be sealed.
3Chock the front wheels, then jack up the
rear of the vehicle, and support securely on
axle stands (see “Jacking and Vehicle
Support”) placed under the body side
members.
4Disconnect the exhaust system front
flexible joint. Suspend the front section of the
exhaust system with wire or string from the
underbody.
5Disconnect the rear section of the exhaust
system from its rubber mountings, and allow it
to rest on the rear suspension torsion beam. It
is advisable to support the rear section of the
exhaust at its front end, with wire or string
from the underbody, to avoid straining the
system.
6Unclip the handbrake cable from the
bracket on the left-hand fuel tank securing
strap.
7Disconnect the fuel hoses from the fuel
level sender unit located in the right-hand side
of the fuel tank. Make a note of the hosepositions for use when refitting. Be prepared
for fuel spillage, and take adequate fire
precautions. Plug the open ends of the hoses,
to prevent dirt ingress and further fuel loss.
8Disconnect the wiring plug from the fuel
level sender unit.
9Disconnect the filler and vent hoses from
the rear of the fuel tank.
10Support the weight of the fuel tank on a
jack with an interposed block of wood.
11Unscrew the securing bolts from the tank
mounting straps, then remove the straps and
lower the tank sufficiently to enable the
disconnection of the remaining vent hose.
12With the aid of an assistant, withdraw the
tank sideways from the right-hand side of the
vehicle. Note that as the tank is withdrawn,
some residual fuel may be released.
Examination
13If the tank contains sediment or water, it
may be cleaned out using two or three rinses
with clean fuel. Shake vigorously using
several changes of fuel, but before doing so,
remove the fuel level sender unit, as
described in Section 8. This procedure should
be carried out in a well-ventilated area, and it
is vital to take adequate fire precautions -
refer to the “Safety first!” Section at the
beginning of this manual for further details.
14Any repairs to the fuel tank should be
carried out by a professional. Do not under
any circumstances attempt to weld or solder a
fuel tank. Removal of all residual fuel vapour
requires several hours of specialist cleaning.
Refitting
15Refitting is a reversal of removal, ensuring
that all hoses are reconnected to their correct
locations as noted during removal.
16On completion, fill the fuel tank, then run
the engine and check for leaks. If leakage is
evident, stop the engine immediately and
rectify the problem without delay. Note that
the engine may take a longer time than usual
to start when the fuel tank has been removed,
as the pump refills with fuel.
