Nalgene makes a fuel bottle in the ½ liter as well as the 1-liter size. I have used them for a number of years with good results. They come with a spout to allow for easy fueling of stoves, lamps etc that is well thought out and easy to use. It stores under the cap upside down inside the bottle. I store white gas, K1 Kerosene as well as ultra pure 1-K Kerosene in mine. They are also rated to take alcohol fuel even though I have not used them for that yet. The newer ones have a place to write on them the type of fuel you are using that bottle for but the older ones I just used a Sharpie to write the pertinent information on them. They have never leaked or smelled of fuel even the one I store in my truck year around.
