Hello Essi friends, I have a problem which has been annoying me for a long time. My Ford loses gasoline and that constantly, actually since I got it. I have to refill the stuff constantly. So about all 600 KM. Also a visit to the ADAC did not bring a solution. It must be a hair crack in the tank, the inspector said. I would gladly remove the problem. Maybe seal the tank from inside. What do I use best? Construction foam or silicone, plastic? That is not supposed to be be so good for the environment, I have heard. Not to mention the danger of fire! MfG Dirk 😉
