LR3/Disco 3
The fuel tank is located on the right hand side of the vehicle, between the transmission and the right hand chassis
longitudinal. The tank is located on a mounting cradle which secures the whole fuel tank assembly to the vehicle. The
tank has a useable capacity of 86.3 litres (22.8 US gallons).
The cradle is attached to the chassis with six screws. When the cradle is attached to the chassis, the tank is positively
secured via foam pads which bear against the central chassis cross beam. A protective cover is fitted to the front right
hand corner of the tank and provides additional protection.
The fuel tank is manufactured from moulded plastic which is a minimum of 3 mm thick. The tank is a sealed unit with the
only internal access being via the pump module flange aperture on the top of the tank.
The flange assembly comprises a pump module flange which contains all external pipe and electrical connections for the
tank internal components, a collar and a clamp. The flange is fitted with a seal which locates in the tank aperture. An
arrow on the flange must be aligned between two moulded lines on the tank, adjacent to the pump module flange
aperture, to obtain the correct orientation of the flange. The collar is located over the flange and is secured with the
clamp. The flange, seal, collar and clamp arrangement meets the sealing requirements of LEV2 emissions.
The flange has a six pin external connector which provides for electrical connections for the level sensors and the fuel
pump. This connector is wired to three push fit connectors on the underside of the flange. A quick release connector
provides for the connection of the fuel feed pipe and breather.
A tank carrier assembly is attached inside the tank and is used to locate the internal tank components. The carrier
provides location for the fuel pump module, the front level sensor, the Roll Over Valves (ROVs) and the front jet pump.
The fuel pump module contains a number of components. The module comprises the fuel pump, the rear fuel level
sensor, the rear jet pump, the pump inlet filter, a second fine mesh filter and the fuel pressure regulator, which is housed
in a manifold that is mounted in the carrier assembly. Only the pump module assembly and level sensors are available as
serviceable components, the individual assembly components are not available separately.
