Driving home recently in my wife's 2009 Vauxhall Tigra 1.8 Exclusive, after a 40 mile round trip, we traversed a particularly nasty speed hump at 5mph in second gear. There was an immediate strong smell of petrol inside the car. Turning into our road 30 seconds later I noticed the fuel gauge indicating empty and the amber low fuel warning light on. The tank had been just over a quarter full so we had lost over two and a half gallons in less than a minute. We parked at home on our driveway, a slight slope and stopped the engine. On getting out we saw petrol was running down the driveway in the rain. Next morning the RAC patrolman who attended as requested, jacked the car up and discovered the return fuel line from the engine to the fuel tank had split at a junction in the pipe near the front bulkhead. He push fitted it back together and all was well. Two thoughts spring to mind. Firstly, I think we were very, very lucky that the car didn't catch fire losing that much fuel in so short a time adjacent to the hot exhaust and catalyser. Secondly, how much longer must we put up with the menace of speed humps?
