FUEL TANK

The fuel tank is made of plastic and has a capacity of appr. 51 litres, including a reserve of appr. 5 ÷ 8 litres. The fuel filler neck is integrated with the main part of the tank and it is fitted with a new type of filler cap. A mechanism inside the cap ensures that it is only tightened to the correct torque; over-tightening beyond the specified value is avoided as the cap will click past the resistance offered by the teeth.

The tank is fastened to the body on level with the luggage compartment floor and rear seat and it is shaped so that it does not interfere with the tubular frame of the rear suspension. Due to the particular shape of the tank a pipe has been added to release the air to the upper section when filling with fuel.

The corrugated pipe on the filler prevents the fuel from splashing out. On the filler there is also a two-way safety valve. An opening is located in the upper section of the tank to house the pump-fuel level gauge assembly and for the multi-purpose valve.
