Fuel Tank
The fuel tank incorporates a single filler neck and check valve, internal fuel pump, internal fuel filter, a sender unit and an
‘on board refuelling vapour recovery’ system.
Fuel Pumps
) X H O 3 X P S
The modular fuel pump is immersed in the base of the fuel
tank. The pump can deliver up to 150 litres/hour. The in-
tank fuel line connects to the external line using a quick-fit
connector in the base of the fuel tank. During normal running, pressu
rised fuel from each fuel
pump passes from the tank, through an 3 micron in-tank fuel
filter to one of the two fuel rails on the engine.
Fuel temperature is measured on the primary fuel rail. If fuel
temperature becomes excessive, the fuel pressure is
increased to prevent fuel vaporisation (boiling).
Fuel pressure is measured by sensors on each fuel rail. The
fuel pressure to each rail is regulated as required by
continuously changing the run speed of the associated fuel
pump. Maximum pressure in the system is limited to 5.3 bar
by in-tank pressure regulators.
A constant head of fuel is maintained in the fuel pump
modules to ensure that the pumps cannot run dry in a ‘low
fuel’ situation.

Jet Pumps
Fuel feed from the fuel pumps is split three ways:
1. Feed to the fuel rails.
2. Feed to the swirl pot jet pump (integral to the FDM).
3. Feed to the externally mounted jet pump (LHS). These pumps ensure that the appropriate pump swirl
pot is maintained with fuel under severe dynamic
conditions.
Filler Neck and Check Valve
Incoming fuel passes through a check valve at the base of the
filler neck. This valve is normally held closed by light spring
pressure. The valve opens under the pressure of incoming
fuel and closes again when fuel flow ceases. The check valve
prevents surging of fuel in the filler neck.
The filler neck also forms part of the on-board refuelling
vapour recovery system. Incoming fuel forms a liquid seal in
the filler neck. Thus any air displaced during fuel tank filling
cannot escape via the filler neck.

Fuel Limit Vent Valve (FLVV)
This valve contains a float which rises to cut off the path for
displaced air when the fuel level rises towards maximum
during fuel filling. This causes a rapid pressure build up in
the tank which triggers the cut-off valve in the fuel delivery
nozzle. This discourages overfilling of the fuel tank.
The FLVV also includes an over pressure relief valve set at
about 2 psi to vent the tank if all other vents fail.
Roll Over Valves
The roll over valves purpose is to vent the highest point of
the tank. If the tank is grossly overfilled (e.g. many clicks over
the normal filler nozzle cut-off), the FLVV will suffer a
hydraulic lock. The roll over vent valve allows venting of the
tank at the highest possible level in this situation.
All three valves allow the tank to breath until it is inverted
when they will close to prevent fuel spill. The fuel level vent
valve controls the fuel height of the tank by creating a
pressure spike inside the tank which shuts of the fill nozzle.
If the vehicle is inverted in an accident, this valve will close
to prevent leakage of liquid fuel.

Evaporative Loss System
Fuel vapour is displaced from the fuel tank during filling.
Vapour is also displaced due to fuel evaporation in higher
temperatures. Displaced fuel vapour is absorbed in the
carbon canister filter located on top of the fuel tank.
During normal engine running , absorbed fuel vapour is
purged from the carbon canister and mixed with the normal
fuel/air charge in the inlet manifold.
System Operation
Displaced fuel vapour leaves th e fuel tank via the normally
open fuel level vent valve and the roll over valves. It passes
through the carbon canister where fuel hydrocarbons are
absorbed. Clean air leaves the system via the normally open
canister vent valve. This valve is only closed during
diagnostic pressure testing of the fuel system.
During normal engine running, the single vapour
management valve in the engine bay is periodically opened,
when negative pressure exists in the intake manifold,
allowing fresh air flow into the open canister vent valve,
through the carbon canister, through the vapour
management valve and into the primary inlet manifold. This
fresh air flow progressively purges any absorbed fuel vapour
from the carbon canister.
Fuel Tank Vents and Control Valves
On-Board Refuelling Vapour Recovery
All of the vapour displaced from the tank by refuelling passes
through a series of valves and through a carbon canister. This
filters out and stores all the fuel vapour and clean air exits the
carbon canister port.

Normal Fuel Fill - Air displaced from the fuel tank during
filling can only exit via the fuel level vent valve and roll over
valves and be forced through the carbon canister. Any fuel
vapour in the displaced air is absorbed in the carbon filter
material. No fuel vapour can escape to the atmosphere.
Clean air then exits the carbon canister, via and additional
filter, to atmosphere.
Excessive Fuel Fill - In the event of overfilling of the fuel
tank, the fuel level vent valve will close at normal maximum
fuel level. Finally the roll over vent valve will close,
completely sealing the tank. Any excess pressure in the fuel
tank will ‘blow off’ via the Ov er-pressure vent valve (part of
the roll over vent valves) in the Fuel Level vent valve
assembly.
Safety Precautions
Operations on fuel system resu lt in fuel liquid and vapour
being present in the working environment. This presents a
very serious risk and the following precautions must be
strictly observed:
Specifications
Warning
Operations on refuelling and the fuel system must only
be performed by personnel who have completed training on fuel handling.
