Not familiar with these as they are not in u.S. But most newer cars have an anti rollover flapper in tank so fuel doesn't leak out in a rollover. You may be able to get a hose there to pump the tank out. If you can reach the vent try removing that hose and putting the hose there.

IF YOU CAN GET TO IT EASILY
REMOVE THE FILL HOSE FROM THE FUEL TANK INLET. SEE IF YOU CAN GAIN ACCESS AT THAT LOCATION, YOU MAY BE ABLE TO GET A "TRANSFER PUMP" (HAND OPERATED) FROM A AUTO PARTS STORE
