With small amounts of fuel, water will extinguish a flammable fuel fire without spreading it.
BTW- I couldn’t find where it stated the Tundra is suitable for Class B flammable liquids. It only mentions grease in the specs. It does say not to store in areas exposed to heat. Could be a problem in direct sunlight. I’d like to know what’s in it, as it’s not allowed to be sold in California.
I'm not a fireman, nor an expert on extinguishing fires, but the experts do specifically say not to use water on a Class B (gasoline) fire.
Here is one rated for Class B fires.
Here is another. As you can see they get very favorable reviews. These use expandable foam to smother fires. It's highly doubtful sunlight alone will cause any issues with them. I've had mine onboard in full sunlight at 90+ degrees since 2015. They're only rated for 3 years use so at the end of last season, after buying a replacement, I decided to try the old one out on a gasoline fire I made on my gravel driveway. It extinguished it in seconds.
These are, of course, certainly not the best fire extinguishers available, but for an easily storable, easily reachable, first response Class B suitable extinguisher for the TI, this is probably the best bet. Certainly better than water or a bulky extinguisher stored inside the hull which would be difficult to retrieve in time, and most certainly better than nothing.
