CLiX for diesel boats is a game-changing innovation designed to revolutionize boat refueling while protecting our waterways. Featuring patent-pending technology, CLiX helps prevent fuel spills—keeping both boats and the environment clean. Its patent-pending technology ensures a seamless, stress-free refueling experience for boaters worldwide. Say goodbye to spills and environmental concerns and hello to effortless, eco-friendly fueling with CLiX. Using the CLiX makes fueling your boat like fueling your car. 5% of all proceeds go directly to nonprofits dedicated to protecting and preserving our oceans. The CLiX Fueling device is designed for traditional fuel ports and should not be used with modern flip-top fuel ports that place the vent at the top. The Diesel CLiX is designed to work with the standard-flow diesel fueling nozzle which matches those used for the fueling of cars. The high-volume diesel nozzle is both larger and has a much higher flow rate than the standard. The High-flow nozzle will not fit into the Diesel CLiX properly and cannot be used with it. Please do not attempt to use the Diesel CLiX with a high-volume nozzle nor try to adapt the CLiX for that use. Doing so will negate any warrantee and could cause the fueling operation to fail putting both the user and the boat at risk.
