Fuel rail causing fires?

Hey guys I know every time someone posts about a fire everyone jumps on the "they were carrying a gas can in the back" bandwagon. But there have been some that claim they weren’t carying a fuel can and still went up in flames. So my question is has anybody had a fuel rail fail? Was there fire? The reason I ask is I will now be taking my 2 year old with me and want to be as flame free as possible so I ordered the Billet rail from rpm and one of my buddies is laughing at me for buying something "I do not need" and doesn’t believe that cheap fuel rail could be the issue.
