The only problem the car has: When filling up, there is a pretty big amount of fuel running out of the big hose / tube that goes over the fuel tank. I made a short video: https://www.youtube.com/shorts/rMgEhv49mDw Things i have noticed: - I can not fill it with the nozzle "fixed" until it clicks when it is full - I can not fill up the tank 100% - 75-80% max - When the fuel gauge is at about 50% the needle starts to "wiggle" very nervous between empty and half full when driving over bumps ect. - The dripping Does somebody have a idea where to start? Air in the tank? Thanks! | ||

The fuel is running out very close to the exhaust pipe so I would recommend not driving it until the issue is resolved. There are several vent lines that you will want to take a look at because at least one is no longer attached or has broken. - There is one about half way up the filler neck that goes to the tank. - There is one that goes up and over the rear door from one corner of the tank to the other. - There should be a vent line related to fuel tank gas evaporation management that goes through a system and then is drawn into the engine when it is running. Then there is the return fuel line. | ||

There is an additional tank installed under the car. From the filler neck for the tank goes a second line to this additional tank. This line was connected with a hose and clamps. The hose had a crack. When refueling, gasoline ran into this line and dripped through the crack. | ||
