Disaster for neighbor

I had a fuel leak in the garage a year ago. By the time I noticed it there was a puddle of fuel and it wasn't going on by smacking it with a towel and I had visions of the garage going up taking my Duster and road runner with it.

Luckily I had an extinguisher to put it out. Unluckily it was a dry powder extinguisher and you haven't lived until you get to clean up the mess those things make. I replaced the spent extinguisher with another dry powder unit, but really need to invest in halon or something that doesn't make a mess or take a chance on having to clean up another mess some day.
