tank, the car stopped runningMy 94 Rolls Royce Silver Spur III was parked for 7 months. I had to jumpstart it. It was rough at first but it later ran smoothly. When I got out of the car, I smelt gasoline, and my garage floor was flooded, I checked the flood on the floor, and it was gasoline. IMy tank was 1/2 full when the car started running, when the fuel was completely drained from the tank, the engine cutoff.. My mechanic came but couldn't find where the leak came from, so he pumped 7 gallons of fuel into the tank and started the car in order to find where the lead came from, this time, not a single drop of gasoline leaked out. We drove the vehicle for a few miles, yet no leak. Is there someone out there who explain this strange event to me?
