Marine Fuel Anti-Siphon Valve Fittings

An anti-siphon valve or check valve is one of the most important safety measures to have on an inboard engine. If a fuel line breaks, these valves will stop the tank from siphoning gas or diesel into the bilge, reducing the risk of fires, explosions and water pollution. By using them to connect gas lines to the tank, fuel will only flow when positive pressure is applied.

Marine Parts Source has the right boat gas tank check valve to update your vessel. They come in different sizes and connection types to match your existing setup, and with rust-proof bronze or aluminum construction, they will last in tough marine conditions. Browse anti-siphoning valve fittings from EVM and Moeller Marine Products that are compatible with major inboard engine manufacturers, including MerCruiser, Crusader, GM and Volvo Penta.
