Fuel Leaks, Vapor Buildup & Stuck Caps Are a Fire Hazard — This Deck Fill Eliminates All Three

Old-style screw-cap fuel deck fills are a liability on the water: they leak fuel vapors into the bilge, corrode shut after a season of saltwater exposure, and require two hands to open while you're trying to hold a fuel nozzle. This flip-top nylon fuel deck fill solves every one of those problems. The built-in flame-arrestor vent safely releases tank pressure without allowing ignition, the high-quality rubber O-ring creates a watertight seal that prevents any fuel seepage, and the one-press safety lock flips open with a single thumb press — keeping your hands free and your deck dry. Made from high-grade corrosion-resistant nylon, it won't rust, crack, or seize up after years of saltwater use.
