Dispersed gasoline fumes or liquid gasoline are not as combustible as most people think. I'm not saying it isn't a problem, but from experience gained in a misspent youth, I personally know that dropping a match in a pail of gasoline, at room temperature, will extinguish the match.
Gasoline only becomes combustible in a fairly narrow concentration (or if it is allowed to vaporize, like from an explosion or exposure to hot metal). If it is much above or below that ideal concentration, it will not ignite. The most dangerous gasoline container is one that is "empty", a few ounces in the average tank on a warm day is an explosion waiting to happen. Think about it this way, most modern cars have electric fuel pumps inside the tank, immersed in gasoline, they use the fuel as both a coolant and lubricant!
If it were as volatile as we are prone to believe, it would not be the general purpose, liquid energy storage media that we have all learned to love and hate.

Its like that plane that everybody said was shot down by a missle on the east coast but the investigation showed the explosion came from inside the fuselage which service records show that there was only a hundred gallons of gas in a tank that holds over a ton of fuel which is barely enough to cover the floor of the tank. The spark came from faulty wiring on the sending unit inside the tank that had lost its protective sheathing and then arced between wires causing the vapors to ignite.
I think they are thinking about rigging all the commercial airliners with a vapor removal system like the goverment uses on military planes. It has something to do with forcing nitrogen in the tank and forcing fuel vapors out to prevent fire. sounds like a good idea.
guess its better to ride with a full tank...

Good point, I was ASSUMING it was removed but it doesn't hurt for someone to actually point that out!On 2006-08-16 07:45, FALCONAROUND wrote:
If it's on your sending unit, why don't you REMOVE it first.... Henceforth removing any fear of sparking an explosive revolution...
