Spill-Proof Fuel Funnel

I made my own easy-to-use fuel funnel with an empty, cleaned-out cat-litter container. I cut a 3/4"-diameter hole off-center in the bottom of the container, then mounted a through-hull fitting and sealed it with Permatex. By mounting the spout off-center, the funnel can rest on the gunwale during fueling. The large capacity of the funnel makes it easy to prevent spills. - Frank Flesch, Toms River, New Jersey
