Gasoline boiling point

Has anyone ever heard of gasoline boiling or catching fire in side engine compartment in 100d ambient weather while driving their Tiger? I have a 66 Tiger with 302V8 and was wondering if this is a problem? Would appreciate and comments you may have.
 
I had an engine compartment fire in my Tiger, and it wasn't in 100F weather. I had a leak in a fuel line, which leaked gas onto the intake manifold. I had just backed my car down my dad's very steep and curved driveway. I immediately got out of the car, popped open the hood, ran up the driveway, and turned on the garden hose in the front of the house. It was not long enough to go back down to my Tiger, but I was able to put the fire out by spraying the engine compartment by standing on the hill above the street. I cannot say if the ignition source was the hot intake or exhaust manifolds or if there was a spark from one of my spark plug wires going to ground.

If you had a fire while driving, were you able to find the source of the leak?
 
Thank you for your reply, I've never had a fire in the engine compartment but have had some friends say because of the high temperature inside the compartment could cause the gasoline to boil with possibility of starting a fire. I'm just trying to find out if this has ever happened to any Tiger owners? Right now it's in the middle of summer in Reno NV with 100d days and a lot of car shows to go to.
 
you have more of a chance with fire from the lucas wiring
 
For gasoline vapors to ignite solely due to temperature (autoignition temperature), the temperature needs to be around 477F to 536F. I surely hope your under-the-hood temperatures do not get that high!

David,

Not to make an example of you... But more a general comment..

If you have a fire in the engine bay, get the extinguisher or hose etc prepared first...then open the bonnet ( hood) as little as possible, or if it's possible to access the location of the fire from under the car, fire the the suppressant from there... The more air you feed the fire the bigger it gets and faster it spreads...
 
Also ,think I've posted this before.. but the Element sticks are a great option ..very light, easy to store in the car and don't cause the damage traditional extinguishers do.

Michael,

Your comments are correct in most situations. What you posted is something that we all should keep in mind. I only wish that the garden hose was long enough for me to take it down to my Tiger. Fortunately, the leak was pretty small.
 
I was sitting at a stop light around '73 and noticed the new paint on my Tiger hood starting to bubble. Something in the Holley carb had leaked and ignited. Even at the ripe age of 20, I carried a fire extinguisher with me. Was unable to determine the ignition source after I covered my engine bay in white powder! It happens!!
