Issue:
Fuel misting may be seen from the fuel tank filler neck, with the fuel filler cap removed
and when filling with Diesel fuel.
Cause:
When the fuel is returned to the tank from the engine, it is deposited into the swirl pot to
maintain the fuel delivery performance of the system.
The re-circulated fuel is hot, so it may sometimes create a mist inside the tank.
When the car is re-fuelled, the mist may escape through the filler neck and can be seen
with a naked eye.
This is a natural phenomenon and can only take place if all of the following conditions
are met:
• Low fuel level in the tank (approximately 10 litres or less).
• Normal fuelling flow rate.
• A temperature difference of 50 degrees Centigrade (or 122 deg. Fahrenheit)
between the fuel inside the swirl pot and the fuel inside the tank (Example: An
engine has been run shortly before re-fuelling and there was not enough time for
the mist to condensate inside the tank).
Action:
No action required. Typically such gentle mist may form and escape the fuel tank if the
above conditions are met.
