A device for detecting the presence of water in a fuel tank comprising a fitting mounted at the lower most portion of said tank having a water sensing alloy on said fitting. The fitting positions the water sensing alloy in the tank in the position where water will tend to collect. The fitting also includes an integrally mounted indicating device such as a go/no-go device or a meter to determine the presence of water in the tank. The length by which the fitting extends into the tank can be used to determine the depth of water in the tank and when the amount of water collected at the bottom or sump of the tank exeeds a predetermined depth it will be detected by the indicator connected externally to the water sensing alloy. A useful water sensing alloy is comprised of a composition of lead, tin, and zinc each being present in an amount of between about 20-45% by weight, with the composition also containing small amounts of up to about 0.1% of copper and/or up to about 1% of either samarium, ruthenium, vanadium or selenium.
