Use a bigger funnel to transfer the kerosene from the bulk container into one of the smaller fuel bottles available at sporting goods stores(REI, Academy etc)then use your smaller funnel to fuel the lantern. Or in place of the fancy fuel bottle, just transfer it to an empty 1qt oil bottle (or fuel stabilizer) I have a collection of empty bottles just for situations like this.
Of course, I have been labled a pack-rat before.
