LJ.4 - FUEL TANK
The 43.5 litre fuel tank is fabricated from Neotec coated steel, and is externally powder coated for further
corrosion resistance. The tank is mounted within the chassis crossmember between the passenger compart-
ment and engine bay, and is secured by two support cradles from beneath. The fuel filler neck connects with
the right hand top of the tank, with the filler breather pipe routed to the centre, and the fuel pump/fuel gauge
sender unit mounted into the left hand top surface. A removeable panel is provided in the top of the chassis
crossmember in the cabin, which provides access to the fuel pipe connections and harness connector. If the
pump/gauge sender unit is to be replaced, the tank must be removed from the chassis.
To Remove Fuel Tank
If necessary, syphon fuel from the tank to reduce the weight before removal.
1. WARNING: The fuel line between pump and engine remains pressurised after switching off the
ignition. Before disconnecting the fuel line, carry out the fuel pressure relief procedure detailed
in sub-section LJ.3.
- Carry out the fuel pressure relief procedure detailed in sub-section LJ.3.
- Disconnect the battery.
It is recommended first to release the quick fit connector located to the rear of the coolant header tank:
- Release the retaining clip securing the pipe joint to the header tank bracket.
- Slide the orange coloured safety lock to allow access to the connector release buttons.
- Surround the pipe joint with a shop towel to absorb fuel contained in the pipework before pressing
the release buttons and separating the joint.
WARNING: Be aware of the possibility of full pressure retention in the fuel line caused by a
system fault.
2. Remove the left hand seat and rear bulkhead trim panel. From the left hand rear corner of the cabin,
remove the access panel on the top of the chassis rear crossmember for access to the fuel pump
connections. Release the quickfit type connector on the fuel vapour line connection to the pump/sender
unit top plate. Prise out the retaining spring clip and withdraw the fuel feed pipe. Disconnect the wiring
harness plug from the pump unit, and from the pressure sensor.
3. Remove the RH rear wheel and wheelarch liner to provide access to the filler hose connections. Release
the filler hose and filler breather hose from the tank spigots, and cap both orifices to prevent debris
ingress and reduce the fire hazard.
4. Remove the engine bay undertray/diffuser.
