Fuel System
The fuel system comprises a rear mounted fuel
tank, an in-tank fuel pump, a fuel tank filler pipe,
a fuel filter and a fuel heater (in the case of
Endura -DE variants) and a number of fuel supply
and return pipes.
The fuel tank is of steel construction and has a
capacity of 54 litres. The fuel tank is fixed to the
vehicle by means of four bolts. Fuel tank
ventilation is achieved via a fuel vapour hose
fitted to the fuel tank and vents into the chassis
crossmember. The fuel tank vapour assembly
prevents fuel loss from the fuel tank if the vehicle
becomes inverted.
The fuel pump is located inside the fuel tank and
is fixed to the top of the fuel tank by a locking
ring. The fuel pump is of the regenerative turbine
type and will deliver fuel at a rate of 80 lph at a
pressure of 3,0 bar. The fuel pump has an
integral fuel tank sender unit and features
excellent hot fuel handling, low noise, highly
reliable operation and integral radio frequency
interference (RFI) protection.
The fuel tank filler pipe is of steel construction
and is fixed to the vehicle by means of two bolts.
The fuel tank filler pipe is fitted with a locking filler
cap, which seals the system.
The fuel supply and return pipes are made of a
combination of plastic, steel and rubber. Plastic
fuel pipes are connected to the fuel tank, fuel
injection pump (in the case of diesel variants) and
fuel filter and fuel resistant rubber pipes are
connected to the fuel rail (in the case of petrol
variants). The plastic and rubber pipes are joined
by means of two steel pipes, which run along the
underside of the vehicle. All fuel pipe connectors
are of the quick release type. Supply pipe
connectors are white or are identified by a white
band and return pipe connectors are red or are
identified by a red band.
The fuel filter (in the case of petrol variants) is
located at the rear chassis crossmember. The
fuel filter clamp is fixed to the chassis rail by
means of two rivets and the fuel filter is retained
by the clamp with a single bolt.
The fuel filter (in the case of Endura -DE variants)
is located on the rear face of the cylinder head,
adjacent to the battery tray. The fuel filter clamp
is fixed to the cylinder head using two of the
bolts, which retain the rear engine lifting eye. The
fuel filter is retained by the clamp with a single
bolt.
Both petrol and diesel fuel filters have a paper
element contained within a steel canister.
The diesel fuel heater (in the case of Endura -DE
variants) is located on the right hand side of the
cylinder block in front of the fuel filter. The diesel
fuel heater bracket is fixed to the cylinder block
by a single bolt and the diesel fuel heater is
retained to the bracket by two clips.
The diesel fuel heater is designed to warm the
diesel fuel in order to prevent waxing at cold
temperatures. The heating element is a
temperature dependent resistance, which has a
positive temperature coefficient, i.e., the
resistance of the heating element increases with
increasing temperature. The heater is fitted with
an integral thermo switch, which prevents
overheating of the heater element.
A fuel shut -off switch (in the case of petrol
variants) is located behind the passenger cowl
side trim panel adjacent to the powertrain control
module. Two screws retain the fuel shut -off
switch. The fuel shut -off switch is designed to cut
the electrical supply to the fuel pump in the event
of an accident or parking impact, thus reducing
the risk of fire.
