Fuel tank

Fuel Tank

The fuel tank is of a plastic construction and is retained to the vehicle by means of two steel support

straps. The fuel tank support straps are mounted onto the underside of the vehicle chassis towards

the front of the fuel tank and bolt to the vehicle towards the rear of the fuel tank. Fuel tank

ventilation is achieved through a fuel tank roll-over valve into an evaporative emission canister which

absorbs fuel tank vapor. The fuel tank roll-over valve is integral to the fuel tank and will prevent fuel

loss from the fuel tank if the vehicle becomes inverted.

Fuel Filter

The fuel filter is of a conventional construction being that of a paper element sealed within a steel

canister. The fuel filter is located on the left-hand front longitudinal member, under the left-hand

splash shield.

Fuel Tank Filler Pipe

The fuel tank filler pipe is of steel construction and is retained to the vehicle by means of two lower

retaining bolts and one upper retaining nut. The fuel tank filler pipe is fitted with a twist-fit filler cap,

which seals the system.

Inertia Fuel Shutoff (IFS) Switch

The inertia fuel shutoff (IFS) switch is designed to cut power to the fuel pump in the event of an

accident. It is located behind the left-hand cowl side trim panel.

Fuel Pumps

The fuel pumps are electric turbine type pumps and are located inside the fuel tank, one on the left-

hand side and one on the right-hand side on supercharged vehicles. They both feature an integral

fuel tank sender unit and each is retained to the fuel tank by means of a locking ring.

Vehicles without supercharger

As the fuel tank is of a saddle design, a fuel pump module and a fuel transfer pump are incorporated.

The fuel pump module located in the right-hand side of the fuel tank transfers fuel to the left-hand

side of the fuel tank. The fuel transfer pump located in the left-hand side of the fuel tank transfers

fuel to the fuel pump module and then the engine.

Vehicles with supercharger

Both pumps continually transfer fuel from one side of the tank to the other, whilst also providing a

fuel supply to the engine.
