Fuel Tank

The fuel tank is located on the right hand side of the vehicle, between the transmission and the right hand chassis longitudinal. The tank is located on a mounting cradle which secures the whole fuel tank assembly to the vehicle. The tank is blow molded from HDPE (high density polyethylene) and has a usable capacity of 86.0 liters (19 gallons).

The cradle is attached to the chassis with six screws. When the cradle is attached to the chassis, the tank is positively secured via foam pads which bear against the central chassis cross beam. A protective cover is fitted to the front right hand corner of the tank and provides additional protection.

The fuel tank is manufactured from molded plastic which is a minimum of 3 mm thick. The tank is a sealed unit with the only internal access being via the pump module flange aperture on the top of the tank.

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 molded into the fuel tank. The flange has a tag which locates in the top of the tank to ensure correct orientation.

The flange has six pin internal and external connectors which provide for electrical connections for the level sensors and the fuel pump. A quick release connector provides for the connection of the fuel supply pipe.

A carrier within the tank provides for the mounting of the fuel suction tube, vent valve, and the front fuel level sensor.

The fuel delivery module is mounted on a bayonet lock ring which is welded inside the fuel tank. The fuel delivery module comprises the fuel pump, jet pumps, the pump inlet filter and the fuel pressure relief valve. The rear fuel level sensor is also mounted on the side of the pump module body.

The pressure relief valve assists engine starting by retaining a pre-set fuel pressure in the fuel supply pipe and the fuel rails. The valve also limits fuel rail pressure due to temporary vapor increase in hot conditions and pressure caused by sudden load changes; a fully open to closed throttle transition, for example.

Only the pump module assembly, the fuel level sensors and the flange are available as serviceable components, the individual assembly components are not available separately.
