Not too good.

It's also the same for those aftermarket foam air cleaners, like you find on lawnmowers. They soak up gas fumes, and if there's a spark, they burst into flames.

A friend of mine bought an old VW Bug, and on the way home the engine caught fire. The VW burnt up, and he walked down the road and hitchhiked home. He only lost a few hundred bucks.

Gas cars burn up all the time, and also travel trailers. I've seen quite a few burning vehicles on the side of the road.
