Leakage from 206 hdi diesel tank

hello good day with my friend, my car 206 hdi has been leaking from the point where the diesel tank is in my car for about a week, when i park my car in the evening and check it in the morning, the bottom of the diesel tank is not as much as a tea glass, I see why the leak was not drying all day long. I got into my mind tomorrow I will stop by industry thanks.

1 tea glass & nbsp; the volume will leak from the bottom of the tank, since there is a leak in the & nbsp; I sanmıoy & nbsp; probably the & nbsp; on the upper sides & nbsp; has. If I don't fill the tank too much, & nbsp; always & nbsp; doing the leak

When I fill the tank, I do not leave diesel after throwing a pistol. The tank is now 250 km, but still the leak continues there. I will check the gold again tomorrow morning. I had no such problems before. & nbsp;
