Misfuel prevention
Mechanical device which prevents filling the tank of a Diesel vehicle with petrol. It avoids the risk of engine damage that can result from filling with the wrong fuel. Located in the filler neck, the misfuel prevention device appears when the filler cap is removed.
When a petrol filler nozzle is introduced into the fuel filler neck of your Diesel vehicle, it comes into contact with the flap. The system remains
closed and prevents filling. Do not persist but introduce a Diesel type filler nozzle.
Operation
It is still possible to use a fuel can to fill the reser voir. In order to ensure a good flow of fuel, do not place the nozzle of the fuel can in direct contact with the flap of the misfuel prevention device.
This equipment will become available during the year.
