Madem Zen, did you find it? I did eventually find it. It is under there and is way up there. You have to crawl under to see it, but it is there and you don't need to access from under the bed. Also, once you do the fuel filter changes, be prepared to push the primer bulb about 400+ times, even after filling both filters up with diesel.
