I'm going to be parkiing my '92 LC in Las Vegas, out in the sun but under an aluminized cover, between desert trips. I've got one of those nice new NATO-style gas cans, but now that we're a couple of weeks away from our initial trip I've started thinking about leaving that gas can sitting around in that heat. Gas tanks and caps must have some vents, but cans?
I was initially thinking that we'd be sure to leave the can empty, but the more I think about the less comfortable I am. Presumably it's got a good seal, but at some temperature anything could explode. Since vapors, not the liquid gasoline, are what explode, it would probably be safer to leave the thing full, but somehow that doesn't sound so good either. If I leave the cap inside the truck and open a crack, the interior may smell like gas from then on. But this will just be in some RV storage lot, so I don't have too many other options.
Any ideas?
