Well THAT explains a lot.
I wouldn't expect that to cause any problem in the old carburetor days, but I would think headlice would really gum up a fuel injector.
I wonder what attracts the little suckers into gas tanks.
They say a sense of wonder keeps you young. I've been wondering about our current President for 5 years now and I don't think it's working.
But...
Stop and consider that back in the old carburetor days, gasoline was, well, gasoline. Except for a smidgen of tetraethyl lead. Which got the environwenies boxers in a wad and they started playing with gasoline so that today a large percentage of what they pretend is gasoline is composed majorly of substances not entirely unlike gasoline...
Oh, and headlice probably won't like a gasoline hair rinse, but don't light a match or smoke a cigarette for a few days. If you aren't troubled with headlice, but have made some trips to the more uncivilized portions of the world, like, say, Detroit... you might find that you have picked up a friendly Taenia saginata or one of its kin.
If you find that you have an uninvited tenant living in your abode and you are fresh out of praziquantel, you can use the old jungle remedy.. Take a teaspoon of sugar and soak it in gasoline (or kerosene, or diesel, they're all alipathic) and swallow it down. Your occupier will positively disseminate segmentally...
It does taste a but difficult though...
