Are crash fires usually from the gascolator exploding like a molotov cocktail? Or other fuel components? I'm worried that the day I have to mush into trees or bushes after an engine failure, or make an otherwise decent landing in rough terrain, that my bird is going to explode as the gascolator shatters.
It depends a lot on the severity of the impact. This is why turning the fuel off is the most important pre-crash item. It's quite likely the gascolator will be broken if there is bottom cowl damage, but if there is only a cup or two of fuel in it, the float bowl, and the lines from the valve it will not be the movie type of explosion. If the crash is such that the fuselage is crushed where the fuel lines are upstream of the valve, well, that is much worse.
Planes with a header tank like cubs are a different story. If that is punctured there is a gallon or more of fuel spewing into the cockpit!
The bottom line is that many more deaths occur from improper forced landing technique than post-crash fires. Get the fuel, mags and master off, latch open the doors, and fly the airplane into whatever is available just above the stall speed, and you will have a high probability of surviving.
Don't try to stretch the glide or maneuver violently within 200 feet of the ground just to reach a better looking area!
