kerosene is similar but different, it is much lighter and combusts at lower temps, i would suggest not using it, but it's better than starting with a dry filter i suppose, you could always just fill the filter with diesel fuel or heating oil. for what a 10 minute trip to the pump would cost i would just use diesel or heating oil. but like i said kerosene will work. haha, just do w/e, i don't think anything will get hurt either way
