The fuel tank is located on the right hand side of the
vehicle, between the transmission and the right hand
chassis longitudinal....

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...

The TdV6 vent system is different to the system used
on the petrol models. The TdV6 vent system comprises:
•two Roll Over Valves (ROV)
•one Liquid Vapor Separator (LVS)
•breather spout.
The vent system is mounted on the...

The front ROV is located in the front left hand corner
of the tank. It is attached by a moulded clip to the main
beam of the carrier. The ROV is connected to the LVS
by a corrugated tube.
Both ROVs vent directly into the LVS. Any liquid fuel
is separated from the vapor in the LVS and drains back
into the tank via the front ROV.
The LVS vent outlet is connected to the underside of
the tank flange. The vent line is then routed from the
flange to atmosphere at the top of the filler neck. This
line allows...

The sensor comprises a series of 51 film resistors
mounted in an arc on a ceramic surface. The resistors
are wired in series with individual contacts. A soft
magnetic foil with 51 flexible contacts is mounted a
small distance above the film resistors. A magnet,
located below the ceramic surface, is attached to the
sender unit float arm. As the float arm moves the magnet
follows the same arc as the film resistors. The magnet
pulls the flexible contacts onto the opposite film resistor
contacts forming an...

the pump outlet pressure becomes too high, the regulator
controls the fuel pressure in the feed pipe by allowing
some fuel to return to the swirl pot.
The regulator is subject to pump output pressure and
controls the pressure of the fuel delivered to the HP
injection pump to a maximum of 0.5 bar (7.25 lbf/in2).
At pressures above this figure, the regulator opens,
decaying the pressure supplied to the HP injection pump
by allowing fuel to flow back into the swirl pot. The
primary reason for the regulator...

Bracket2
Fuel feed to engine (HP injection pump)3
Fuel return from cooler4
Fuel return/air bleed to tank5
Water drain valve6
Filter canister7
Clamp bracket8
Fuel feed from pump module9
The fuel filter is located behind the fuel cooler, at the
rear of the engine and is protected by the engine
undertray. The fuel filter assembly comprises a bracket
and the filtration element which is contained within a
canister.
The filter canister is attached to a circular bracket which
is...

The fuel filler head is positioned at the rear of the
vehicle, above the right hand rear wheel. The filler head
is covered by a moulded plastic cover which is
electrically locked when the vehicle is locked. The filler
cap is a conventional screw in type which is secured to
the vehicle with...

incorporates an insect trap at its termination near the
filler head. The fuel filler pipe locates in a short flexible
hose attached to the tank and is secured with two worm
drive clamps.
A smaller pipe, which is not associated with the fuel
system, is attached to the side of the fuel filler pipe. This
pipe connects to the rear differential and provides
breathing for the differential case. The pipe terminates
near the fuel filler head.
