I'm pretty religious about the clamps but I guess I let the hoses go too long and recently had one split under pressure (fortunately just after start-up on a cold engine on a cold day).
It sprayed a fine mist of gasoline all over the engine and I am sure that if it had ignited, it would have been fatal.
