strangest thing has happened, at the weekend I started the car in the garage and reversed out.checked the garage floor and saw a small puddle. Checked under the car which was idling in the drive and there was petrol running out just ahead of the drivers side rear wheel.Put the car back in the garage and sent for a mechanic. He checked the car out today ( 3 days later ) and found no leak from the fuel lines,pump or filter.He is puzzled and I am too!!!
The car is an 320 sl r129
any suggestions?

thanks
