Actually my 1984 318I could have caught fire once when a rubber line connected to a fuel regulator cracked pouring gas on top of the engine. But it was winter and I caught the strong smell of gas in time before the car warmed up enough to ignite the fuel. There are lots of old cars here in NYC with fuel deliver issues that could cause a fire. I once witness a car at a stop light, an old wagon being used by a painter, spring a gas leak creating a puddle that later caught fire when the car tried to continue on.
