15 Fuel pump module The fuel tank is a saddle type tank, blow moulded from HDPE (high density polyethylene). The tank is located forward of the
rear suspension and is mounted using two metal straps. The tank is a sealed unit with the only internal access being through
the fuel pump module aperture on the top of the tank.

The fuel pump module flange has a six pin external connector which provides the electrical connections for the fuel pump and
both fuel level sensors. A quick release connector provides for the connection of the fuel feed pipe.

The flange is fitted with a locking ring and seal. The seal locates in a groove on the tank. The locking ring locates and clamps
on the encapsulated ring that is moulded into the fuel tank. The flange has a tag which locates in the top of the tank to
ensure correct orientation.

A carrier within the tank provides for the mounting of the passive side jet pump tube, vent valve, ROV and liquid vapor
separator (LVS), level sensors and passive side drain.

FUEL PUMP MODULE

1 Magnetic foil 2 Spacer 3 Ceramic surface 4 Magnet 5 Resistance film The film resistors are arranged in a linear arc with resistance ranging from 51.2 to 992.11 Ohms. The electrical output signal is
proportional to the amount of fuel in the tank and the position of the float arm. The measured resistance is processed by the
instrument cluster to implement an anti-slosh function. This monitors the signal and updates the fuel gauge pointer position
at regular intervals, preventing constant pointer movement caused by fuel movement in the tank due to cornering or braking.
A warning lamp is incorporated in the instrument cluster and illuminates when the fuel level is low.

The fuel level sender signal is converted into a CAN message by the instrument cluster as a direct interpretation of the fuel tank contents in liters. The ECM uses the CAN message to store additional OBD (on-board diagnostic) 'P' Codes for misfire detection when the fuel level is below a predetermined capacity.

JET PUMP

The fuel system incorporates two jet pumps. One jet pump is integrated into the fuel pump and draws fuel from the RH side of the fuel tank. The other jet pump is located on the fuel delivery module on the RH side of the tank. There is a pipe that is located in the LH side of the tank that allows fuel to be drawn over from the LH side of the tank, delivering fuel into the swirl pot. The jet pumps operate on a venturi effect created by the fuel at pump output pressure passing through the jet pump. This
draws additional fuel from the LH side of the tank through ports in the jet pump body, delivering additional fuel to the swirl pot.

FUEL VENT VALVE

The fuel level vent valve is located in the upper half of the tank and is connected into a separator which is connected to the
Roll Over Valve (ROV) tank breather. The main purpose of the fuel level vent valve is to control the fill volume of the tank.
During filling, air trapped inside the tank and a small amount of vapor is passed via the fuel level vent valve to the tank
breather. The air and vapor mix then vents to atmosphere through the breather. During filling, when the tank reaches its full
level, the fuel level vent valve closes and prevents air/vapor passing through to the tank breather. The resulting back pressure
causes refueling to stop automatically.

The fuel level vent valve is always open when the fuel tank is below full, providing an unrestricted air/vapor outlet to the tank
breather.
