Not sure how in the hell you would see fire damage from a flash ignition from fuel vapor. Just because there was a leak doesn't mean that the fire would go back through the fuel lines and catch anything else on fire. Read up on fuel vapor. There didn't even have to be a leak that was squirting out after the car was off. Could of been a smaller pool of fuel that accumulated under the intake manifold and got just enough of a spark of the exhaust manifold in order to ignite. When in a sealed area a fire will flash burn, and actually put itself out after the flash if there is no more fuel to burn. An injector leaking could do that easily and wouldn't allow a stream of fuel to actually be there after the fuel pump shut off. There is also the chance that the fuel line pressure valve could of leaked too. For those that don't know there is a schrader valve very similar to a tire valve on the fuel rail where fuel line pressure is checked.
The other thing that could be possible would be the A/C system can build enough pressure and blow if there is a blockage and the compressor keeps pumping pressure through the system, the condenser or one the lines could blow, and possibly be ignited.
Anyways this obviously wasn't a bomb. It was either fuel igniting or something else that blew the top layer of sheet metal out like a jiffy pop popcorn container.
