Fuel Delivery System Components
The Land Rover V8 fuel delivery system comprises the following main components:
l
Saddle type fuel tank
l
Fuel injectors

Non return fuel rail

Fuel pump

Fuel Tank
The fuel tank is constructed from moulded plastic and is mounted under the rear seat just forward of the rear axle.
The fuel tank has a 100 Litre capacity and activates a low fuel warning lamp in the instrument pack when there is 12
litres in the tank. The tank is of the saddle tank design with a siphon jet pump in the left side to transfer fuel to the right
side where the fuel pump is mounted. The fuel is delivered along pipes that run along the underside of the vehicle to
a fuel rail mounted on the engine.
Fuel Filter
The fuel filter/pressure regulator is mounted on the lower right hand side of the tank. The charcoal canister is mounted
at the front of the tank on the right hand side. The components are covered by a plastic under tray to protect them
when driving off-road. The undertray has an inspection cover to enable access to the charcoal canister and the fuel
filter.
Fuel Pump
The fuel pump comprises a pump, sender unit, pot and venturi. The unit has an integral filter inside the pot. The pump
unit operates at 3.5 bar for 170–205 l/hr (the V8 has a maximum operating requirement of 90 l/hr).
The pump is controlled by the ECM via the fuel pump relay.
