I nearly had the same thing happen with mine. I found that the rubber cone shaped seal inside the pump was not lubed enough causing it to stick and flip inside out. This was causing the fuel to pour out the pump. I now make sure my pump is well lubed before every trip. I think there is a set of instructions for disassembly of the pump that came with either the stove or the Expedition Service Kit if you have one.
