this at the boat shows next year and is should reduce all the concerns about fuels in boats.
it can also be used in Gas cans.
the substance reduces all vapor to 20% saving fuel costs as well.

I will sell you a magic substance that will not take any extra volume in your tank, and will prevent your gas tank from exploding. In fact, it's already in there. It's gasoline
! The head
space in your gas tank is too rich to burn or explode unless the tank is completely drained (even then it's unlikely). In the even less likely event that your gas tank is shot with a bullet, it's still not going to explode. If you are truly unfortunate enough to have your gas tank shot and the fuel leaking out contact open flame, then yes, I can see where the vapors from the leaking fuel will ignite. I'll add a liability rider in my substance's packaging for that possibility.
The only thing you might prevent with whatever they're selling would be BLEVE, and if you've got the conditions for that you have ***way*** bigger problems than the tank going up. Race
cars use fuel cells to keep the fuel *in* the tank when they crash, not stop the tank from exploding. In the tank it's much safer than spread out on the tarmac where it can get a good vapor going and cause ill will.
That's not to say that gasoline aboard is infallable. It's like anything, you have to handle it properly. The knife you use to prepare dinner will just as easily kill you if you let it. Yet we generally call the knife "safe" and the gasoline "not." The idea is to keep the fuel contained, and to take measures like ignition precautions and ventilation / blower precautions as if the vapor were present.
I carry gasoline for the outboard, and will soon have a Honda generator
too. My concern is more about covering the gerry can so that the sun doesn't degrade the plastic than fire prevention. Short of stumbling into the can with a lit flare I can't see how I could get it to light off. We have a honda genny in a compartment on a truck at work and have zero issues with it leaking. I worry more about the fact that guys will run it for two hours and then slam the compartment door closed and drive off with the exhaust
system still crazy hot. Not enough to lose any sleep over, but I grin at the thought of the fire truck rolling down the street on fire. I figure that the heat is more likely to ignite the paint
than the fuel, though.
