Yes…a vehicle with a fuel leak is known as a rolling bomb. Stop driving the vehicle and have it towed to a good mechanic. Labor and parts vary widely from region to region so it would be better to get the estimates locally. Besides…you really don’t know the extent of the problem. It could need a small repair or a very large repair. In any event, driving this car is dangerous and it could wind up costing you your life or the lives of others.
